Honestly,I have no idea why would people even dislike this incredible movie! This is one of the best Japanese live action movie I have ever seen! Besides the fact that it is highly unlikely that the high school students is able to defeat those enemies,the warring states period part is quite confusing as the story did not explained anything about it and the fact that one of the scenes there wasn't any blood on the sword after one of the high school student killed one of the enemies.The rest of the scenes was okay.Overall,it is such a great movie with an interesting plot and excellent actors such as Arata mackenyu,Nobuyuki Suzuki and Haruma Miura.I was literally crying whenever there is a scene of Haruma Miura in the movie.
