Kimetsu no Yaiba: Mugen Ressha-hen is the epitome of japanese cinema.
First, the Mugen Train arc is just outstanding, as much as it was in the manga. From the opening scene presenting Oyakata-sama and his lost apprentices to the final fight (which is one if not the best I've seen in my whole life) featuring Rengoku vs the Upper Rank Demon Akaza, the story and its pacing never let me down and I was on the edge of my seat for the whole showing.
As expected from an ufotable production, animation is god-tier, as seen in the 2019 TV anime series. Sound was even better than in the anime and the action scenes' sound design were remeniscent of Enen No Shouboutai, which was the best part of this particular anime in my opinion. I loved the sound effects used in fights, especially when fire is involved. Voice acting is as good as ever, and the characters are awesome, especially Rengoku.
Overall, I'd recommend seeing this movie to anyone who loves movies even a tiny bit, it's a masterpiece of japanese cinematography, with thrilling action scenes and heartbreaking dramatic moments. Even with the COVID-19 circumstances involved, I'd really recommend seeing this in a IMAX theatre if you can, for the optimal experience (art work looks even better on a umongous 4K screen, trust me). Don't miss this.
