    I didn't see DEMON SLAYER: KIMETSU NO YAIBA - THE MOVIE: INFINITY CASTLE in September because I hadn't seen the series. I'm glad I listened to someone who said it (mostly) works on its own. It pushes you into the deep end, definitely, but the water's fantastic. What an invigorating experience. Damn.

    Props to all my fellow parents of middle schoolers who sat through "Demon Slayer: Kimetsu No Yaiba The Movie: Infinity Castle" on opening night. I don't know how she did it amidst all the explosions but the mom next to me managed to nap for like an hour. Absolute legend.

    I know we’re busy with the implosion of the world last superpower, but it really shocks me how little attention is being paid to the fact that the (155min!!!) animated film DEMON SLAYER: KIMETSU NO YAIBA - THE MOVIE: INFINITY CASTLE opened a monster, making SINNERS look like a slow indie release.

    We deal with clunky anime titles all the time and yet this feels worse. “Demon Slayer: Kimetsu No Yaiba The Movie: Infinity Castle: Part 1” isn’t good, but “Demon Slayer: Kimetsu No Yaiba The Movie: Infinity Castle: Part 1 & Grogu” is rough, man.

    Demon Slayer: Kimetsu No Yaiba The Movie: Infinity Castle (2025) Visually stunning. Every scene looks absolutely amazing. Some incredible fights in this one but it still makes time to pull on the heartstrings. If you can see it on the big screen then I encourage you to do so! #FilmSky 🎥

    Demon Slayer: Mugen Train won’t make you a fan of the franchise if you aren’t already, but it will absolutely strengthen your love for it if you’re already an established fan. It’s also an anime film that covers just about everything; it tries to tear at your heartstrings, it has two awesomely sinister villains, it has significantly kick-ass action sequences, and it further develops a supporting character you were only briefly introduced to previously. Mugen Train is outrageously funny and…

  • Rene @The_Bad_CriticTMDB reviews · Jul 8, 2021

    Waited for so long to see this and at the end it did not disappoint. It's a rich story of the demon slayer and stuck in a world of weirdness and dreams. stuff gets real on the train and ends up being a filler for the series of the beginning for the next series I assume . Good watch for a weekend.
