Director Takashi Miike, is one of those directors you will either love or hate, theres no half measures in any of his work (apparantly he shoots around 5 movies a year) and this film is no different...
Basically a gangster movie, a Thaiwanese gang(the dragons claw) are looking to push the local yakuza gang out of the lucrative Shinjuku area of Tokyo. Specialising in drugs, gay prostition, extortion and the sale of human organs. One cop (as always)is determined to bring this to a halt before more blood is spilt, while his younger brother is the lawyer of the dragons claw gangs leader.
What follows is a brutal and often disturbing look at how this seedy underworld district operates. There are no good guys in this film, the lead cop is often as reprehensible in his actions as the men he pursues, but each characters lack of morals in 'buisness' is often counter-balanced by their concern for the people they care about in private (the cop wants to get his brother away from this life so he doesnt end up like him) which means the interplay between the characters is often interesting....
However this film does have its flaws, Miike has a propensity to want to shock and revolt his audience, to expose our own lack of concern that we watch these violent movies by making them as horrific as possible. When it works its compelling, when it doesnt, it just seems pointless. There are certain scenes which seem to have no meaning, the cop, leads a suspect into an interrogation room and questions him whilst another cop sodomises the suspect (no really) to make him talk, in Miikes world anything goes and it doesnt matter if it doesnt make sense. This is all well and good, but at times you get the feeling hes doing it purely for the sake of it, and gives wieght to those who critisce him as a one trick pony...He's not, he's better than that and overall, this film is a pretty good indicator of his talents...
