I read the manga so I knew what would happen but seeing it animated just brought another level of heartbreak to me. With the amazing animation and background music, I was engrossed in this movie. Also, the final fight scene between Rengoku and the Upper Rank Three demon was probably one of the best fight scenes I've watched so far. Granted, I haven't watched many fight scenes. Still, it was such a pleasure to watch.

Rengoku is awesome in this film, and you understand why everyone looks up to him.

I just have to state the most obvious thing though, this animation is truly breathtaking, if you love the show you're going to love this movie.

To be honest I just had a great time watching it, me and my friends all loved it, not to mention the fight scenes are impeccable.

Definitely an A+

Had no idea what I was walking into, that's as frank as I can make it. Out of nowhere my kid has a love for Demon Slayer and here I am along for the ride. But she's seen the show and I had no context. Here we have a bunch of people on a train, one of them really excited about his bento box ("Umai! ... Umai!"),another wearing a boar's head, now everyone's asleep and pretty soon the fighting begins . . .

That said . . .

It is a gorgeous film. The battle scenes are exciting, the animation is superb, and the high quality bears out (Tanjiro's water effects are crazy).

Purely on a visual level, I enjoyed this film. I have no doubt that any self-respecting anime fan is scoffing at my ignorance, but it is what it is. Mugen Train is easy on the eyes.
