Demon Slayer: Kimetsu no Yaiba the Movie: Mugen Train is a movie in the anime series. It is a Japanese style movie. Cartoonish, yes it’s animated. If you’re into these types of movies I guess it’s okay to see it. I’m not a fan of them so I wasn’t real impressed with it but again if you’re one that likes these type of movies I would imagine you would be happy to see it. It’s 117 minutes long. Me personally I would give it two stars but I’m sure those that are fans of this movie would give it much more.
