It seems that this film is mainly destined to teen audiences, because the leads are young adults. It is a social drama disguised in a horror film, that's my analysis; a vitriolic portrait of Japanese youth thru those grown up kids. It is not an European film, no matter the actors, it is sometimes totally f...up in the making of scenes, bloody, brutal, bitter and funny a few seconds later. Not for Western audiences anyway, except the die hard fans of Asian cinema and Japanese in particular. But it is not too long, only ninety minutes, and it makes things a lot easier for me. This is not a crime film, my real cup of tea concerning Rising Sun country films. It is bearable however, and it is also the first movie of a series. Without me though.
