Uh, major plot fault...
At the beginning of the film they state that whoever possess the corpse of the monk rules the king-fu universe. So how the hell would anyone be able to take it from them by martial means? The fact that this gang - and for Christs sake, Drizzle? Who picked that *beep* name? - killed them and stole the corpse without breaking a sweat should probably speak volumes about its apparent worth as a mystical power artifact. LOL!
