Tanjirō Kamado, joined with Inosuke Hashibira, a boy raised by boars who wears a boar's head, and Zenitsu Agatsuma, a scared boy who reveals his true power when he sleeps, boards the Infinity Train on a new mission with the Fire Hashira, Kyōjurō Rengoku, to defeat a demon who has been tormenting the people and killing the demon slayers who oppose it!
An enjoyable cast and a couple of charming relationships are enough to make this a surprise.
Very funny and smart, its shot like a comedy and suffers like most comedies do because of it.
The directors Paul and Chris Weitz -- the American Pie brothers -- have tried hard not to make a tearjerker, and at its best the movie is knowing and tart.
