I went in expecting the animation to carry it after seeing all the high ratings, but it didn’t. This feels like Ufotable’s weakest work to date and I regret giving it my time. Every 3 minutes of actual story is padded with 10 minutes of flashbacks, which destroys pacing and tension, and the constant slowmo shots add nothing, dragging out moments that don’t deserve it. The direction leans on characters explaining what’s happening instead of letting scenes move the plot forward, showing weak narrative control. I’ve read the mid manga, yet the adaptation still manages to be worse. I’d rate this a 0 if thatwere possible, and if you genuinely enjoy this, it’s worth asking what standard you’re using for good anime.

By all means a perfectly fine and well-executed movie. It's a visual feast, the emotional moments hit hard, and the hype and buildup is pretty masterful. If you like Kimetsu No Yaiba, like most people, this is KnY at its best. However, if you're like me and don't like when the emotional moments drag too long (especially in the case of its demons), nothing will save this movie from being Akaza: The Movie for you. His flashback sequence is a good third to half of the runtime. Don't get me wrong, I like how this show presents demons as having humanity, but I didn't pay goodmoney for an IMAX ticket to watch Akaza: Origins. A little flashback is okay, great even, but at some point it drags on too long to be effective when I mostly came to see guys with swords cut other guys' heads off.

I had very high expectations going into this movie, and my expectations were...sort of met? I mean let's get the obvious out of the way, the animation is amazing as always and even looks better than previous seasons, which is just astonishing. Don't get me wrong, there were some parts that were just still frames with dramatic lining (at the very end of the Tanjiro and Giyu vs Akaza fight), but overall the animation was definitely up to par with Ufotable's standards. Besides the animation, I don't really know what else is special about this movie. I liked Akaza's backstory—I thought it was the bestin terms of storytelling among all the other flashback backstories—but I think it would've been more impactful if we haven't seen so many backstories previously to Akaza's. By the time Akaza's backstory was introduced I literally told myself "oh great, another backstory" because I'd seen the same thing a million times beforehand with this show. In fact, this movie has a LOT of backstories, which wasn't really surprising considering it's Backstory Slayer for a reason, but when the show puts too many backstories in it the pacing just feels really disjointed and takes you away from the beautiful action scenes. Anyway, I don't really have anything else good to say about this movie. Kaigaku is a terrible character and literally doesn't matter at all. We were shown Kaigaku like twice before this fight so this fight barely had any significance. If Kaigaku was more frequently shown in the story it would've been way more impactful, but for me it just falls flat. It's the exact same with Shinobu vs Doma. Shinobu as a character hasn't been relevant for a while (mainly because the plot put her aside to do research on demons) and Doma is barely a character that we've seen besides the upper moon meeting back in season 3. I completely forgot Shinobu had a sister and that she was killed by Doma, so the reveal that Doma killed her did nothing for me. This is the one thing Demon Slayer severely lack in to make a story both good action-wise and character-wise. If characters were more memorable and used more often then this movie would be a lot better, but for me, it severely hinders the movie. As always, if you like action, watch the movie. If you like good characters, and don't care about action, don't watch this movie. Or watch it anyway and see if you like it or not.

Oh my God, bruh I'll list the positives because it'll be much faster: - I liked the Douma/Shinobu fight - They said 67 Otherwise, holy shit dude, this movie was so fucking boring. I guess to this movie's credit, damning with faint praise as it is, I didn't literally fall asleep during it unlike Mugen Train but I also was sitting upright in a chair for this one so idk how much you can credit that to the quality of the movie I'm going to try and avoid any major spoilers (if you care that much, I'll post an extended version of this review on my anime list's notes) but it'sfucking Demon Slayer, man, how do you think it went As mentioned above, I liked Douma/Shinobu. Douma had the advantage of being the first villain of the movie so he had a charismatic presence and not much to follow up on, I liked his fighting style and Blood Demon Art, Shinobu's my favorite Hashira so I was invested in the fight, if for whatever reason the film abruptly stopped here, this movie would've gotten, like, an 8. The problem is it goes for TWO FUCKING HOURS after the half hour they spend on that fight. I said Hashira Training could've been a movie, if Infinity Castles 2 and 3 plan to be this long, this could've been a whole TV season and it reeks of money-grubbing (which, to be fair, is apparently working out very well for them) that it's not. For comparison, Kizumonogatari: Koyomi Vamp, the compilation film of three separate films (the longest of which doesn't even break 90 minutes) is 2 hours and 24 minutes, a little shorter than this one movie. All 3 of the Fate/stay night Heaven's Feel movies are roughly half an hour shorter for a Ufotable trilogy, hell, even MUGEN TRAIN was half an hour shorter. And the problem is this movie is three separate fights (only one of which involving the titular Akaza) and the latter two are mid af. I think that's part of the problem with this movie, it feels blatantly like "TV content cut into movies for money". At LEAST Mugen Train had the decency to be a self-contained arc, so it made sense why it was a movie (relatively speaking, especially since they just made it a TV arc anyway). I haven't seen the Reze movie for Chainsaw Man but that is also ONE arc that they're adapting into a movie. I would imagine the rest of Part 1 would get adapted into Season 2 so again, that's fair. This is just one third of the final arc split into a movie for no reason. It's 3 fights grafted together for 2.5 hours of sugary junk food. To all the people who whined and bitched and moaned about Zenitsu being a shitty character, he's just another generic aura farmer now, and the opponent he gets is quite possibly the most generic, S1-tier villain we've ever gotten out of the Upper Moons. I honestly didn't even remember this guy existed, I had to look him up on the Fandom wiki to see if we've ever even met the guy. I guess we did so... uh... fair play. The Akaza fight is, of course, the one that gets the whole works. If you've seen Demon Slayer before, I'm sure you can guess how the fight goes. At this point, I was completely checked out of the movie. It sure looked Ufotable Pretty. I've heard a lot of complaints about the pacing and it is godawful. You get a flashback for Douma. You get a flashback for Shinobu's older sister. You get a flashback for Zenitsu's opponent. You get a flashback for Akaza that lasts, like, 20 minutes. This movie does not give a fuck about your time. I'm not going to remember a single thing that happens in this movie by the time part 2 comes out. Not a single character interaction, not a single joke, not any of the Hype and Aura Moments, not the Ufotablecore LiSA song (I can't even remember the Aimer one, I think I've already automatically replaced both the Aimer and LiSA songs with songs from Fate in my head), nothing. It even ends with Muzan going "yeah, so what? This shit doesn't matter" I mean, he said it, not me.

I have been enraptured in a multiplex after a very long time. This was an absolutely fabulous beginning to the 'begining-of-the-end' arc of "Kimetsu No Yaiba". For everyone who has followed the series,there couldn't have been a better movie. "Akaza Sairai" encapsulates everything that's great about the anime while giving you an excellent cinema experience: right from character interactions to their backstories to the animation to the music. It takes you through the whole spectrum of emotions while furthering the story at a great pace. The backstories were so beautifully done. You can't help but feel bad even for a Demon. Thus,I have been surprised toread bashing from some corners regarding the pacing of the movie. As if the backstories & flashbacks didn't add to the gravity of the moment & as if they took anything away from the scene itself! It seems that a lot of people went in just to see what has been making waves in audiences around them & why are so many people hyped to watch this new,shiny thing. Naturally a lot of first timers would've watched the movie. This is what happens when an anime becomes so mainstream: it becomes a little pinch on the wrist some times which gets reflected in people with inane expectations getting disappointed. As for me,it will be very tough waiting for the sequel.

One word. Pacing. It felt exactly as one would fear: like a bunch of disjointed anime episodes stitched together nonsensically in a way that ruined the pacing. Like to compared to Mugen Train which had a complete arc and felt like a complete movie, this not only felt like a Part 1 in the worst way, it felt like episode 1, episode 5-7 and episode 13-16 of a 24-cour stitched together. There were 3 main arc/plot threads in this film and one of them (Kanao/Shinobu) couldve been removed entirely and placed in the 2nd movie, it isn't resolved here, doesnt connect to any ofthe other arcs and was basically filler here. And then there's the ACTUAL filler (ie 10+ min of people aimlessly wandering). Of the two remaining arc standout imo was the Zenitsu arc which while standard, was executed very well. Yes the Senior was a bit comically evulz, but his and Zenitsu's relationship and clashing inferiorities was handled pretty well. Top arc WOULD'VE gone to the Akaza fight... if they didn't Jebait us 3 times and then insert a 40minute flashback arc that was super by the books, predictable and tropey. And the worst part? Everything about that fight up until the flashback was SO GOOD. The battle, the animations, the lessons learned and battle thoughts. The backstory that was SO TASTEFULLY HINTED AT UNTIL THAT POINT. Like Koyuki and Keizo appearing to hold him back for a few frames was so well done and SHOWED SO MUCH in such little time. And then they just HAD to TELL US all of it again over 40 minutes after the fight was already over. And it didn't tell us anything new. Everything we saw in those 40 minutes was predictable by anyone who's ever seen any movie or anime before. and none of it topped those subtle character flashes up until then. SHOW, DON'T TELL. Whatever, rant over. Would've been better as another season of the anime.

Visually, the movie is stunning—Ufotable once again delivers top-tier animation with fluid, detailed fight scenes. The atmosphere is strong too, especially with Akaza taking the spotlight this time. But the pacing is where it falls apart. The flashbacks drag on for way too long, killing the hype of the battle. Instead of getting a relentless, high-energy fight, the momentum keeps getting cut off by repetitive backstory sequences, and the tension just fizzles out. And when the movie should be reaching its climax, what we’re left with is a forced emotional moment—Akaza “meeting” his wife. Sure, it’s supposed to be sad, but it feels cheap and manipulative, asif the film is desperately trying to squeeze tears out of the audience instead of delivering a proper peak to the battle. In short, it’s a good movie from a technical standpoint and worth watching for the visuals, but narratively it leans too much on dragged-out flashbacks and forced drama, leaving the climax feeling flat.

Demon Slayer: Infinity Castle – Movie One ⚠️ This is a partially analytical and constructive review that discusses themes and production choices, but avoids plot spoilers. The full review with spoilers and analytics can be find in my blog. “The final night has fallen on a thousand years of evilness. As the rising sun ascends, its peaceful brightness becomes the blade that ends it - once and for all.” I want to begin this review by saying that I love Demon Slayer. When I first encountered it, I dismissed it as strange and mediocre. Over time, though, it grew on me so deeply that I can honestly callit a series close to my heart. With this incredible movie, Demon Slayer transcends its own medium and reaches far beyond what anime has traditionally achieved. After so many years, it feels like a second family to me a wholesome, epic, and beautifully intimate story that has now reached its ultimate expression: the final battle, the last night. In this review, I’ll be looking at the story’s themes, direction, and emotional impact, highlighting both its strengths and weaknesses, and doing my best to stay reasonable, respectful, and constructive all without giving away key plot details. 🕊️ More than Animation This film elevated Demon Slayer to something far more sentimental and spiritually inspiring. Some critics dismiss the series as “carried by animation, no story,” but this movie proves how wrong that surface-level criticism is. While the animation is indeed stunning, what carries this film is not its visuals but its story and soul. The film asks us to look deeper than appearances. The animation may dazzle, but its true power lies in the values and emotions woven into the narrative. Even the weakest anime can resonate deeply if a viewer finds personal meaning in it. With Demon Slayer, the surface presents a simple, linear shōnen battle story animated at the highest quality. But beneath that surface, the series offers something richer and more enduring. 🌱 Storytelling and Character Depth The author of Demon Slayer crafted a short, simple, yet emotionally uplifting story. By giving even side characters dimension and believable motivations, she made them feel alive. They have reasons to exist, goals to pursue, and backstories that explain their choices. That alone isn’t revolutionary, but the way this movie presents and concludes its battles is. The movie shows that victories and growth aren’t always about flashy powers or convenient plot devices. Characters earn their successes through courage, determination, and emotional strength. The story emphasizes that true strength comes not only from skill or physical ability but also from compassion, persistence, and the willingness to protect others. Demon Slayer manages to balance dazzling action with meaningful character development, making it more than just a visually impressive film, it’s a story about humanity, growth, and the enduring power of empathy. Review - Part One ❄️ Akaza’s Humanity Akaza’s backstory and his tragic life with Koyuki shows how his desire to be strong masked deep loss and vulnerability. His “strength” was born of weakness and grief. Without a guiding purpose, he would have collapsed into despair, and so he clung to the idea of becoming the strongest. *But ultimately it was Tanjiro’s selfless actions, words and soul that let to help to reignite Akaza’s human past and his memory of his bride Koyuki that defeated his demonic path. Akaza was never truly evil. He fought with heart and despised weakness not out of cruelty but out of pain. When he finally turned his anger inward, it was an act of realizing his own weakness and reclaiming his humanity. Throughout Demon Slayer, good and evil are shown to be far closer than we assume separated not by destiny but by a single belief, an idea, or even a heartbeat. 💕 Themes of Empathy and Compassion This is what makes Demon Slayer unique: its symbolism of empathy, compassion, love, and kindness. Muzan, in his greatest cowardice, underestimated this. By imprisoning the Demon Slayers in the Infinity Castle, he believed he had neutralized them. But he failed to recognize what these humans carried with them the fire of the heart, the strength of love and compassion. When truth and goodness emerge, evil can no longer hide. It cannot run from the sun, and it cannot escape humanity. 📝 Closing Thoughts of Akaza Fight Tanjiro and Giyu triumphed because their humanity overwhelmed evil, their warmth of kindness extinguished the coldness of darkness not because of plot armor or a last-minute gift of power. This conclusion was the result of character-driven storytelling, emotional growth, and a spiritually uplifting narrative. For this battle, I give it 8.5/10. Its story was emotionally touching, although the action scenes were missing some adjustments from reaching a directionally climax level of entertainment it was beautiful and manga accurate. Part Analyzes, 💥 Action and Choreography of the Akaza fight. The movie delivers action at the highest level. The battle was dynamic, layered, and visually impressive, showcasing the skill and growth of the characters. The animation style is breathtaking, with intricate movements and beautifully choreographed sequences that make every clash feel significant. At at the same time unfortunately, the fast pace sometimes makes it hard to track the finer details. These fights showcase the strongest characters at the peak of their abilities. While they should be fast and powerful . Almost impossible to follow by human eyes, some moments could have benefited from slightly wider shots or slower timing to better show the flow of action. Certain techniques are glimpsed only in part, which slightly reduces the feeling of their impact. At some point of the battle you couldn’t process really how that attacks were played out or how is that block, kick or unexpected attack was carried out in the heat of the moment. Nevertheless, the movie succeeds in making the fights feel emotionally meaningful, not just visually impressive. 🌟 Character Perspective in Battle What makes these sequences stand out is the focus on character insight. Tanjiro thinking through his choices and strategies, reacting to the circumstances and analyzing his opponents. This focus on mental and emotional engagement adds depth to the action, making victories feel earned rather than convenient. 💡 Creative Choices and Style The movie occasionally favors stylistic flourishes and dialogue over fully animating every attack. While this gives certain sequences a unique visual tone, a few moments could have been more fully realized to heighten impact and clarity. I felt that for example, Nakime blood demon art was underutilized. Her manipulating the castle platforms and walls, giving the slayers more pressure and difficulties would have made the fight more intense. Nevertheless the fact that these would have made it better they didn’t underline the emotional and thematic weight behind the battles, showing that strength isn’t only physical it’s also emotional, strategic, and moral. ✨ Emotional Moments One of the recurring elements that gives Demon Slayer its heart is the way it handles the emotional side of conflict. Characters are seen supporting one another, reflecting on their actions, and quietly honoring those they encounter. Like the famous moment when Tanjiro carelessly screamed at Akaza from behind, I would imagine if this scene would makes you think of the classic Naked Gun facepalm moment, but Tanjiro isn’t screamed out of carelessness; he’s shouted out of conviction: “I’m here, I’m doing this, I’m giving everything I have.” In classic shōnen fashion, that declaration marks the emotional climax of the fight. It’s also a quiet gesture of respect. Rather than silently stabbing someone from behind, Tanjiro lets him know what’s coming almost like a samurai duel where the finishing strike is signalled in advance. This layer of empathy and compassion adds a unique dimension to the story, making it more than just an action anime. Overall, the action sequences are thrilling, visually stunning, and emotionally resonant. Some minor pacing and clarity issues prevent them from reaching perfection, but the combination of spectacle, strategy, and sentiment keeps the viewer deeply engaged. Analytical score: 6.5/10 The potential for a 10/10 was there, but execution left room for improvement. 📩 Themes and Messages of the Akaza Battle The story in Demon Slayer: Infinity Castle - Akaza returns; goes beyond flashy fights. At its core, it’s about compassion, empathy, and the strength of the human spirit. True power isn’t just physical; it comes from courage, kindness, and the willingness to do what’s right, even in the face of overwhelming challenges. The series shows that understanding, empathy, and integrity can have a profound impact, sometimes even more than sheer strength. 💭 Emotional Resonance One of the reasons Demon Slayer resonates so deeply is how it balances action with emotional depth. The series reminds us that outcomes are shaped not only by skill or power, but by choices, values, and the courage to act with integrity. Moments of empathy and kindness often carry more weight than moments of violence, highlighting that shared humanity can overcome even the greatest obstacles. The movie leaves a lasting impression because it emphasizes these spiritual and emotional truths. It shows that strength is not just about winning, but about staying true to one’s values and connecting with others on a deeper level. Review - Part Two 💥 Zenitsu’s Moment One of the strongest points of this movie is how it shows character growth. Zenitsu, usually crying and hesitant, faces a challenge that pushes him to his limits. For the first time, he confronts his fears directly, showing confidence and focus in a way that’s both inspiring and satisfying. He was fully present, locked in to face his former senpai, Kaigaku, who had only recently fallen to demonic power. This sequence highlights Zenitsu’s philosophy: true strength comes from mastering oneself, not just one’s techniques. Even with limitations, he demonstrates creativity, skill, and individuality, proving that dedication and belief in oneself can surpass raw power alone. The story also contrasts they path; Kaigaku, who have lost their way is emphasizing how choices, mindset, and inner strength shape outcomes. While Zenitsu, it’s a reminder to us that growth comes from courage, persistence, and the ability to act with integrity even when facing overwhelming odds. Overall score: 7/10. 📊 Zenitsu’s Growth and Lessons This part of the movie highlights Zenitsu’s growth in a remarkable way. He faces one of the toughest challenges in the story, and it’s a moment where his calmness, focus, and courage shine through. Even when facing an opponent with great power, Zenitsu shows that dedication, skill, and belief in oneself matter more than raw strength. On the other hand, the direction and pacing of this fight weren’t far from problematic, leaving several opportunities underused. Just as in the previous fights, Nakime presence felt minimal, which at the end of the fight could have made the battle even more epic, using the castle to help Kaigaku, but even when the characters are not fighting, the castle doesn’t seems to endanger casual slayers or wounded soldiers.. which doesn’t really make sense although it wasn’t in the manga, but that would make it reasonable at least as long as Nakime herself wasn’t actively fighting anyone. The biggest misstep was the handling of Zenitsu’s final move. It felt rushed and lacked the impact of a true Thunder-style attack. Both the direction and the pacing undercut the moment, leaving the fight analytically weak. Some parts of the action could have looked better and the direction was a bit odd at times, but the heart of Zenitsu’s journey still comes through. His growth shows that with discipline, staying true to yourself, and inner strength, you can push past fear and uncertainty. Analytical score: 5/10 Bit rushed, oddly directed. Review - Part Three 🦋 Shinobu’s Courage and Resolve One of the most memorable moments in the movie highlights Shinobu’s bravery and intelligence. Despite physical limitations and challenges, she demonstrates how discipline, creativity, and inner strength can turn perceived weaknesses into a unique advantage. This battle reminded us that determination and skill can shape outcomes, even against seemingly insurmountable obstacles. The opposing forces in the story show a contrast between care and cruelty. True danger often comes from those who underestimate or disregard others, and this part of the film emphasizes that strength alone doesn’t define impact choices, empathy, and courage do. The animation is beautifully executed, with creative choreography and precise, engaging movements. While some visual elements felt slightly different from previous installments, I have to re-watch when it will be available to be sure about the quality and sharpness of details.. Still, the character moments and story totally made up for it, turning it into an emotional and satisfying showcase of Shinobu’s growth and ingenuity. 📩 Takeaways This segment underlines that courage, intelligence, and kindness can outweigh sheer power or cruelty. It emphasizes the value of resilience, strategy, and belief in oneself. Despite her physical disadvantages, Shinobu managed to overcome her inner fear. It shows that there’s nothing you can’t do if you’re mentally stronger than all the forces trying to convince you otherwise Battle score: 8/10 (Emotionally powerful, mentally encouraging messages and epic moments) Overall Shinobu Fight analystically gets a 7.5/10 Analystically I wouldn’t changed much, as all the breathing styles of Shinobu were clear to understood though out the animation. I felt only the colors and overall the aesthetic of the drawing slightly newer or changed that what we use to in Demon Slayer. Which comes to my conclusion. 💬 Final Thoughts, The movie as a whole is visually stunning. It felt like some small details were missing, and the characters weren’t as detailed or as colorful as they used to be. Now the studio relies more on lighting effects on subjects and characters instead of rich colors, which I wouldn’t really call an upgrade. The movie could have benefited from a brief recap of key past events to strengthen the sense of closure for long-time viewers. As this is indeed the final Arc, the final night of the story. 📝 Conclusion Demon Slayer continues to capture hearts worldwide, and it’s easy to see why. While it may not be the absolute best anime ever made, it stands as one of the defining works of this generation. It’s a story worth following closely, not just on the surface. At its core, Demon Slayer is about the heights humanity can reach when we believe in ourselves, work together, and act with kindness and perseverance. Even in the face of seemingly insurmountable challenges, the series shows that empathy, courage, and love can triumph over darkness. What sets this series apart is its balance of emotional depth, strong characters, and meaningful storytelling. Battles are not just flashy they convey strategy, inner struggle, and growth. The power system and narrative is simple yet symbolic, and the animation elevates every moment, making the story feel alive and immersive. Characters are symbolic, their actions and struggles reflecting larger truths. Tanjiro is like the sun, and his Water Breathing flows like life-giving rivers. Kanao is like a delicate flower and when she meets him, she begins to bloom, warmed by Tanjiro’s soul, nourished by his words, like sunlight and raindrops giving her strength. Each character, their breathing style, and their struggles carry deep metaphorical meaning, showing us that humanity can achieve extraordinary things through love, companionship, and perseverance. Demon Slayer: Infinity Castle - Movie One is not just animation; it’s storytelling brought to life. Ufotable understood the depth of this story and they have managed to bring depth and soul to every scene. If you look only at the visuals, you might see beautiful animation. But if you look at the animation, you will feel the story itself; the emotions, the lessons, and the humanity woven into every frame. Demon Slayer stays true to what anime was originally meant to be. Anime was created to help us face our inner demons, to make the impossible possible, to show that peace can overcome hatred, and that even the most evil beings deserve another chance , even if that isn’t realistic. That was the point of anime in the first place. Humanity, Sympathy, Compassion, Peace, Brotherhood, Discipline. The will, to never give up. Those who fight for peace often seem weaker than those who declare wars, but Demon Slayer shows us that strength comes from the heart, from truth, and from perseverance. This story isn’t just for humans , it’s for humanity itself. Thank you for taking your time to read my review!

It’s a fun movie, especially for fans, but there were quite a few things that bothered me. Some continuity errors, the pacing, the soundtrack choices, and even the animation itself. The movie starts off strong—great use of CGI and some amazing visual direction—but as it goes on, you start to notice the quality dropping, with less fluid animation and a lot of static panels. The soundtrack has that classic Ufotable vibe, with synthetic and electronic sounds that fit really well in Fate works, but for me, they didn’t quite match the theme of Kimetsu. The pacing also threw me off, since it often felt like I was watching back-to-backanime episodes. The acts didn’t flow well together, and there were too many climaxes and resolutions that didn’t really land at the right moments for a movie. I won’t say much about the continuity errors to avoid spoilers, but if you’re the type who pays attention to small details, you’ll definitely notice them. That said, I still recommend watching it—it’s fun and emotional, and that’s really what we’re looking for at the end of the day.

Demon Slayer never fails to disappoint. As for the animation, as usual, it's way above average. Except for a couple of awkward looking CGI moments, everything looks magnificent. Great management of the camera angles. The soundtrack, another masterpiece. It helps create the perfect cool and epic atmosphere for battles, in perfect coordination with the animation. But that's the minimum expectable from such a commercially successful anime. The bad thing: story and pacing are as mediocre as ever. Almost everything in this anime has been limited to character backstories. Very few characters have received a proper development in the present before leaving forever. Most of them barely had the time to fullyinteract with each other, but they're forcefully shown to have developed deep bonds. The movie is, once again, full of backstories, flashbacks, as well as battles with the characters just throwing techniques randomly. Of course, sometimes alternating with moments in which they have their typical dialogues and sentimental moments to build up some feelings around them. However, grief doesn't last much because the movie switches suddenly into another battle scene. Not to mention that the dialogues are too simple and shallow, as in many other battle shounens. At least, a good thing is that the power ups got a better building than in the rest of the anime, where they mostly occured inexplicably in the middle of a battle. Too many events happening in a single movie. It would've been better as a set of OVAs followed a shorter movie focusing only on the most important demon.

Demon Slayer INFINITY CASTLE Movie This movie isn't recommended for viewing due to several aspects, such as the numerous flashbacks and their placement. Yes, I think it's a good movie, but not the best. Why everyone gave a rating of 10 is unreasonable because this movie is mid. Review: Animation and grafik:9/10(ufotable cook) Story : 7/10 (It's quite simple) Art style: 8/10 (ufotable cook again) Emotional moments: 7/10 ( It's just a little bit stressful not impressed) Pacing movie : 8/10 ( The storyline is quite fast and simple) Rating : 7/10 ( It could be 6/10 because it's overhyped and overrated (mid) Just for fun I will wait for part 2 of thismovie trilogy even though it is not the best but it is worth waiting for (I hope ufotable improves on that)

I am not much of a Kimetsu No Yaiba watcher to be honest, I did watch a few episodes of the series and The Movie: Mugen Train which also links to To the Swordsmith Village arc , To the Hashira Training arc and is link to this movie they call it "Mugenjou-hen - Akaza Sairai" in English they call it the Infinity Castle. Keep in mind this is part 1 of the movie which the plan to make 2 more movies out of this for the fans and turn it into a Epic Battle Royal. Story Kagaya Ubuyashiki's traps and subduing Tamayo, MuzanKibutsuji retreats in his super dimensional stronghold, the Infinity Castle, and also traps the Demon Slayer Corps inside and they must fight their way in random mazes full of demons and Upper Rank Demons. Who will live and who will survive this battle? Animation Ufotable did a great job with the animation very impressive work with its mixture of 2D Animation and 3D animation using close up angles and such detail with action of slow-motion made it interesting .The color pallet was beautifully made on screen conveying a story. Music "Yuki Kajiura and Go Shiina composed the film's music The film's theme songs were "Taiyō ga Noboranai Sekai" (太陽が昇らない世界; lit. 'A World Where the Sun Never Rises') performed by Aimer, and "Zankoku no Yoru ni Kagayake" (残酷な夜に輝け; lit. 'Shine in the Cruel Night') performed by LiSA" The background music did okay to convey the tone of the story and movie having done the epic fights it felt like Inuyasha style music could of work well for this flim. The Final thoughts Great animation, great fight scenes, but... you might be disappointed if your a fan of the series. I am not going to spoil it because its going to make some fans rage or like how it ends. I understand this is a 3 part movie I only watch part 1 seeing how fitting 155 minutes into a movie only to to show 4 epic fights. I hope it will continue with the next movie that will soon come out. I still gave it a 6 the structure of the whole story was going off the rails there only a few scenes of Mitsuri Kanroji none of it fan service.

Demon Slayer Infinity Castle is a film I’ve wanted to see, despite not being a huge fan of the franchise. As an anime fan, I always want to see anime films in theatres whenever I can. Sadly, I missed out on seeing Mugen Train back when it came out. As far as new shonen of its type I’ve always preferred JJK and Chainsaw Man over Demon Slayer, but I do like it okay. But, seeing this movie on the big screen is worth it just for the visuals. Even the harshest critics of Demon Slayer agree that the series has always lookedamazing, and this movie looks amazing. I love the look of the Infinity Castle, as well as how it was animated. The backgrounds are stunning. The fights are amazing, and the film is mostly action. There are some good character bits as well, from Tanjiro, Zenitsu, and best girl Shinobu. But the character that got the most attention in this film is the, you can call him, the main villain of this film, Akaza. I’m sad that other best girl, Mitsuri, didn’t get much to do in this. Hopefully, the next movie will fix that. I will say, of the two movies, Mugen Train is the better one, mainly because it feels more like a movie structurally. Mugen Train was a complete story in itself, while also setting up future events. This film just feels like a few episodes of the series compiled together. It doesn’t have a great structure as a film. It’s not newcomer-friendly at all. Mugen Train was somewhat of a newcomer-friendly film, but not this one. The movie begins right in the middle of the final battle, with little context as to how we got here, and it ends right in the middle of the fight. The makers just assume you’ve seen everything up until now and just go. If you haven’t watched anything Demon Slayer before this you’ll be confused. Casual fans, like myself, will likely still enjoy this, but you fight find yourself a bit lost in the beginning. I haven’t watched Season 4 of the anime yet, and so I was taken aback a bit by how the film just hits the ground running with little context as to what happened. The film is long and can leave you feeling exhausted by the end. While the battle against Akaza was amazing, it dragged on a bit too long for me. Also, I hated what happened to one of my favorite characters in the story. Worse, it happens pretty early in the movie, so I was left a little bummed out for most of it. The film is a must-see for hardcore fans, and I’d even recommend it to casual fans. I don’t think it’s as good as most people say, but it’s still a fun movie, especially visually. I’d give it a 7.5 out of 10, but round it up to 8 for this review.

This movie was an interesting experience for me. I'll preface this by saying that I'm not a big fan of Demon Slayer, I never got behind why it was popular other than the pretty looking animation. I didn't believe I could watch something that boring and bland story wise even if it looked this immaculate and perfect. So a few things I'll lay out that make me dislike Demon Slayer in general (I've watch S1 and Mugen Train movie): - The show treats the audience's time like scrap on the ground: there is unnecessary explanations for things that are obviously happening on screen, there's like negativesubtlety, and the show's not even trying. Maybe actual kids would find this helpful, if it didn't had so much blood and decapitations being its main focus. - Most of the characters, especially the protagonists in Demon Slayer are basically cardboard cutouts, they have no real personality other than the one quirky trait associated with them: the coward, the earnest one, the idiot (wait all of them), the passionate one, the horny one, the loud one (wait that's all of them). - While the animation looks incredibly good, it adds little if the magic and powers themselves are somewhat generic and straightforward. To the audience, Water Breathing Stance 7th Slash does not make any difference with Water Breathing Stance 5th Stance in practice, they all look the same flowy water-like and nothing else. - Demon Slayer thinks Loudness = Comedy, which is just incredibly grating to my ears, and completely unfunny. That outta the way, this movie was aight. There's barely anything in terms of story. They waste no time at the start which somewhat filled me with hope for the movie's pacing, but it immediately tanked with the 5th Seat or whatever started throwing his totally boring backstory. This will be a repeating phenomena throughout the movie, where extremely drawn out backstories interrupt the sakuga impact frames and smooth flowing combat sequences and bring the pacing down to a crawl. And these godawful backstories somehow should make us empathize or understand these borderline cannibals. It doesn't help to watch the cardboard cutout "characters" desperately claw victory while the literal protagonist is so incompetent he has to be guided throughout the movie. This weakness really pops up to the forefront of the movie as it gets extremely unbearable to watch these nincompoops somehow power of friendship their way into winning unwinnable fights. The demons are equally one-note in terms of actual character and devolve into growling insults at the protagonists and pull out some last minute BS to just severely damage them. The titular Akaza is back for the second time in a Movie, and finally we see his backstory, which comes up at the last 40 minutes of the movie, and is decently written. Even so, the way it's in between actually interesting fight scenes takes away from both the fights and the backstory. The runtime of 2hrs 30mins was completely unnecessary, it could have felt much tighter with a 30-35 minute reduction of the scenes of the characters reacting to shit they see in front of their eyes to point out to the audience. Maybe all of this sounds like nitpicking, but I just wish Demon Slayer was actually good and treated its viewers' time with respect.

I binged the entire series in three days and caught this movie in Japanese theatres. Honestly, it suffers from major pacing issues. If this had been presented as episodic anime, it might have worked fine. But as a film, I expected a consistent flow from start to finish; but that just wasn’t there. The biggest problem is the sheer number of flashbacks. Flashbacks can be powerful when used sparingly, like for a last-minute reveal or portraying a character’s dying thoughts. Here, they’re constant, and some drag on for what feels like 10 minutes or more. At one point in the middle of an intense action scene,we suddenly cut to what felt like a 30-minute flashback. It kills the tension completely. I’ve watched hundreds of films in the same theatre, and this was the first time I felt physically restless halfway through because the pacing was that off. There was even a point midway where it felt like the movie was over, simply because the tension had dropped to zero, and not in a comedic or intentional way. The story and visuals are still solid, but as a theatrical experience, this installment falls short compared to the rest of the series. The music, however, was epic as ever; as a music producer, I really appreciated how it was used to build atmosphere. People around me were crying because they were moved by the touching scenes, which speaks to how powerful the score was despite the pacing flaws. Not recommended for cinema. Better to watch it at home, in bits and pieces with toilet breaks (come to think of it, many people were taking toilet breaks). Score Breakdown: - Story: 7/10 (dragged down by excessive flashbacks and poor pacing) - Animation: 9/10 (Ufotable’s visuals remain top-tier) - Sound: 10/10 (epic score, excellent atmosphere) - Character: 4/10 (only a handful were properly portrayed; the rest were sidelined with minimal screentime outside the intro and finale) - Enjoyment: 5/10 (moments of brilliance, but hard to sit through as a film) Overall: 6/10

Don't bother wasting your time and money watching this in theaters. Just wait the web release. I was really looking forward to watch this movie after the latest episode of the Hashira training arc. But this isnt a movie, its a TV show episodes compacted in 2hours Flashbacks were unbeareable, pacing is garbage, story is garbage Dialogues are the most mundane shit you could ever listen Motivations/backstory of Demons are so simplistic you wonder who the fk wrote this and thought it was a good idea. Fights as usual were top notchSound work incredible/10 Voice Acting incredible/10 Its such a shame to waste such talented animators on this garbage.

Infinity Castle – Spoiler-Free Review Visuals (Animation & Art): 9/10 As expected, Demon Slayer once again delivers breathtaking animation. This film pushes the series’ reputation even further, with fluid motion and stunning landscapes. Many shots feel downright cinematic, creating moments that are not only gorgeous but also impactful. Sound & Music: 8/10 The soundtrack and ambience work well to complement the film throughout. The OP/ED are solid, with the artists delivering excellent performances that match the overall vibe. While some tracks can feel a little repetitive, the energy and atmosphere they create still keep things engaging. Story & Writing: 6/10 The story isn’t the film’s strongest point. While the backstories—especially forthe demons—do add emotional weight, they sometimes feel overused and slow the pacing. A bit of exposition is fine, but here it leans too heavily into flashbacks, which can drag down the momentum. Characters: 8/10 Fans of the series will feel right at home here. The cast delivers exactly what you’d expect—no betrayals of tone or character—and each highlighted character gets at least one standout moment. Enjoyment / Vibe: 9/10 For me, Demon Slayer is all about the vibe. The atmosphere, combined with the high-quality animation and music, creates a sleek, enjoyable package. The story might be average, but let’s be real—that’s not why we’re watching Demon Slayer. Final Verdict: 8/10 If you’re a fan of the series, you’ll definitely enjoy Infinity Castle. It delivers big moments, stays true to what makes the show popular, and is a fun experience on the big screen. Yes, the backstories sometimes go too far, but that’s just part of the Demon Slayer formula—and honestly, I’m okay with it.

Demon Slayer: Infinite Backstories was a very mixed viewing experience. At times it would be incredibly entertaining, only to become painfully boring, and then return to being an amazing experience. Then again, only Demon Slayer could do that. It's been like that for nearly the entirety of this anime. Firstly, this movie is stunning . So stunning, Ufotable ran out of budget towards the end of it(not even kidding). Seriously, the lighting and composition of this movie is so impressive and the production is just stellar—you can hear each sword slash gracefully, the animation and camerawork is just beautiful. This has the best fighting chereographyin all of anime, except towards the end(cuz Ufotable needs to save money for the second and third movie). EVERYTHING, from a production and direction standpoint, is masterful. This movie is gorgeous. Aforementioned, the cinematography really is amazing. And really adds so much to the world that is The Infinity Castle. Filmed at all different types of unique angles and styles, the weirdness and eerieness of Muzan's Infinity Castle is portrayed masterfully. The score only enhances those aspects of the movie and makes the more gentle human moments all the more beautiful. Or at least, does the best it can. And the fights are so incredibly immersive, they just suck you in. Until you get cut off from one of the best fights you have ever seen in your life by the 7th backstory of this movie. And then you get reminded that you are indeed watching Demon Slayer. From here on, every critique I make will be as vague as possible. A lot happens in this movie which I wouldn't want to spoil. But I will touch on most parts of this movie. It's actually kind of a myth Demon Slayer simply attempts to be a typical shounen and nothing more. It really does try to explore and tackle a lot of questions. Meaning through characters like Rengoku. The idea of true immortality through Muzan and Ubayashiki. What nature and circumstance does to humans through the numerous demons and their stories we learn of. Demon Slayer tries to explore so many different ideas. However, what made Demon Slayer gain it's infamous title as a generic boring shounen carried by animation is because it explores these ideas in the same manner repeatedly through the same formulaic way time and time and time and time and time again. Its honestly and actually amazing something like ep 8 of The Hashira Training arc exists within Demon Slayer, where an idea is actually explored in this anime without using a backstory to do so. Its also amazing Demon Slayer explored ideas(in that episode) that arent just what circumstance does to humans and why kindess matters and/or what meaning is to a person. It has explored what circumstance does to nature wonderfully with Gyutaro and Daki(and its the only time it worked well). And it has explored solidly well what meaning is with Rengoku(only time it worked well). Yet, it constantly regurgitates these same ideas again and again without ever evolving the idea or dissecting it in a new way. And its always through stupid long ass backstories. Nothing made this more clear to me than this movie. Just get back to the fighting man, the characterization and overall narrative sucks ass. How could it not? Its doing the same thing I've seen it do several times. And its not doing anything different. The characterization of this movie sucks. I had just had to say it again. There is such an impactful fairly early on into this movie. And it involves Shinobu. Yet, the movie glazes over this with her. It happens, and then that's just it. I'm sure in the third movie, more justice will be done to what happened in that pivotal scene with her, but this movie really handles it poorly. Whatever man, anyway, it feels like every character in this movie gets a backstory. No seriously, like if you have an actual character design, you are VERY likely to get a backstory. And whats worse is that some characters get backstories to build their relationships, when it was previously non existent. Seriously, rather than organically introducing the opposing character and/or growing these characters together so that the actual eventual conflict with these characters just feels natural, it does it through a backstory. Are we deadass? That's horrible writing. This movie must have a bet or a goal or something, it hits all the cliche backstories: backstory to strengthen main character or side character? That's one. A backstory to build a previously non existent relationship as to 'create tension and suspense' instead of actual good writing and characterization? Oohhh, thats two. A mf backstory where you, once again, explore THE SAME IDEAS you have explored, through EVERY SEASON of this anime? ITS THREE. JACKPOT, WE HAVE A WINNER. What are we doing here man? How can a movie be so buns and so peak at the same time? For the most part, I kinda enjoyed myself. Some moments didnt hit as they should have because it was something done before in Demon Slayer and were written worse(yeah, I'm talking bout Akaza specifically, I said it) and/or just didnt feel like it was a scene of enough importance, despite it very evidently being one. Again, this is a very fun movie when it's doing bs Demon Slayer stuff and really focusing on the fights. Really, I'm telling YOU, the fights in this movie are among the best in fiction period, if not the best in fiction, and truthfully that's enough to make it semi worthwhile watching the movie. But, as reiterated throughout the entirety of this review, whenever this movie attempts characterization or tries to explore an idea, it's just so ahh. Cuz its nothing new. I've seen Demon Slayer do it before and way way better. And unfortunately, I know the future movies will be more of the same. Regardless, this movie was still 6-7/10ths(😂)fun, despite all its multiple flaws. I didnt even talk about how they constantly used the trope of seeing a loved one to strengthen the characters/around the moment of death. Almost every story beat of this movie is so cliche. Despite that, aforementioned, I still kinda enjoyed myself. That's how great, immersive and enjoyable the fights were, and enjoyment is what matters the most, right?

You can tell this is an anime series and not a movie. The direction and pacing of the movie feels like very separate situations without any relation between them. The background stories are too long and cuts the climax of the movie. I feel like you could do a better job combining combat with the background of the enemies. Especially for the last fight. At the end of the movie you don't get the feeling of a shonen-like final or any cliffhanger making you expect the next movie. Besides that you will still get the undisputed high quality level of demon slayer and get reminded ofthe beauty of animated movies.

Some of the most eye popping beautiful and smooth animation I’ve ever seen, especially sustained for this long of a time, but at the same time, there were definitely things that could probably have been cut or streamlined. There are a lot of shots of the castle, people running around the castle, fodder fighting, or the fanservice feeling “look at your favourite character fighting and oneshotting a no-name demon” sequences at the beginning which added probably 15-20 minutes to the runtime that didn’t necessarily have to be there. That and there are a lot of flashbacks that break up the pacing a bit strangely, withit going for long, beautiful, smooth high speed fights to a slow flashback about someone’s backstory and then back to the fight again. It’s a format that works a lot better in manga where you can control the speed of reading and can get through material faster, as compared to a movie where you’re stuck with the flashback’s pace until it ends. Still though, it was a great experience to watch in theatres and if you have the spare cash or like Demon Slayer, it’s worth a shot.
