A Lot or a Little?

The parents' guide to what's in this movie.

What Parents Need to Know

Parents need to know that Demon Slayer: Kimetsu No Yaiba: The Movie: Mugen Train is a full-length film that continues the popular Japanese anime series Demon Slayer. Both the series and film have gruesome monsters that are known as demons. Expect lots of fantasy/action violence, with plenty of body horror and bloodshed, as well as instances of forced suicide. There's also a bit of strong language, including "hell" and "dammit." On the plus side, underlying the violence is a focus on the importance of letting go of selfish desires for the greater good, and there are also themes of family, teamwork, perseverance, compassion, and concentration. The film is available both dubbed and with subtitles.

Emotional and Sad movie is not as violent as the show

This Movie was very sad and emotional as a character dies in a hard way. I don't think it deserves it's MA15+ rating and should be lowered since it is not as violent as the show. Otherwise I think it's a really good an emotional movie.

Great Continuation of the Anime!

This movie was a great continuation of the anime. If your child enjoys anime, and can watch movies in the marvel franchise, I think you should be fine. The main bad for this movie may be sadistic and a few chickens short of a coop, but it gives you a warm feeling, and the animation sent a chill up my spine. You should watch the show (available on Netflix, Hulu, and Crunchyroll) before watching the movie. It doesn’t hurt that it has a couple of awards under it’s belt as well.

What's the Story?

In DEMON SLAYER: KIMETSU NO YAIBA: THE MOVIE: MUGEN TRAIN, heroes Tanjiro Kamado (voiced by Natsuke Hanae), Inosuke Hashibara (Yoshitsugu Matsuoka), and Zenitsu Agatsuma (Hiro Shimono) are given their next slayer assignment on a public train. The team and their mentor, a high-level Demon Slayer named Rengoku (Satoshi Hino), must defeat one of the strongest demons they've encountered so far -- one who has the power to control dreams.

Is It Any Good?

This fun, lively film acts as a heartfelt extended episode of the Demon Slayer series. The characters in Demon Slayer: Kimetsu No Yaiba: The Movie: Mugen Train bring their same charm and passion to their battles. The action is exciting and flashy but easy to follow. Despite some frightening imagery, the film pushes important lessons for many of its characters, such as being able to let go of the past in order to move forward.

Although the storyline is fairly straightforward, certain information from the series is needed in order to fully understand who the characters are and what their ranking means within the Demon Slayer universe. Despite this, viewers who haven't seen the series can still find entertainment in this film. But know that the level of horror and use of suicide in the movie may be too intense for younger kids.
