For me, this is not the most memorable of this period of the 2000s and for the Asian crime film industry. OK it is fast paced, maybe too much, and there are too much confusion with the characters. Anyway it is the Asian trademark: Honk Kong, Korea or Japan. It is bloody, brutal, sensitive but in such a way that it is mostly hard for western audiences to perfectly follow; only die hard buffs of this kind of Asian stuff can really appreciate. But at least it is not a comedy at all, despite what some users say.
