This movie is the first of Miikes triad society trilogy, and the trilogy kicks of to a great start. The movies in the trilogy are only connected thematically, and these themes are actually apparent in all his films, if you look close enough. Shinjuku Triad Society is about a cop trying to prevent his kid brother from getting too involved with a rather extreme gang of outsiders, struggling their way to the top of Tokyos yakuza. The kid brother is a lawyer, and the triad gang is becoming increasingly in need of one, as the movie progresses. The movie takes place in a very harsh environment, and is therefore pretty violent and tough. Miike has done worse, but since this is a serious movie it hits you very hard. As usual there is also a lot of perverted sex, mostly homosexual in this one. The movie is in many ways a typical gangster movie, but with a great drive and true grittiness. If you've only seen Miikes far-out movies (Ichi the killer, Fudoh etc.) this is worth checking out since it is sort of a compromise between his aggressive over-the-top style displayed in those movies and his more serious side, as seen in the other films of the trilogy. And as always with Miike, there are at least two scenes in this that you'll NEVER forget (see it and figure out which ones for yourself).
