The Mugen Train used to be one of my most anticipated movies of 2020, and the Demon Slayer manga has been a great part of my quarantine life. However, I have to say that this film is quite perfunctorily made. Most of the dialogues spend 15 minutes conveying emotions and information that could've been condensed into 3 minutes. Such pacing certainly works for a season-long anime so that you get the most out of each character, but is excessive to the point of tedious for an adapted screenplay. Additionally, the movie focuses on the transition period from season 3 to the Hashira Training Arc, which seems like unnecessary work since it's not an independent story like the Mugen Train. Instead of spending so much time explaining the context, why not make a film about the actual Hashira Training? Aside from the complaints, all the action sequences are spot-on as expected. The segment where the Wind and Serpent Hashira explored the mansion is perfect in length and smoothly animated, and seeing their breathing styles in motion is all I could ask for as a manga reader. Though I'm all for the Infinity Castle Arc to come as soon as possible, I'd ask that Ufotable take as much time as needed to perfect the animation. As a former global phenomenon, Demon Slayer deserves a proper end.
