Van Damme is surprisingly convincing in both of his roles (if you thought you could never take him seriously as a serial killer, this may prove you wrong), and the film is efficiently directed by Ringo Lam, who choreographs some high-powered action sequences and one or two outstanding set pieces. But the story is rather poorly thought-out (the clone supposedly helps the cop find the killer, but he isn't really very helpful and usually the killer finds them first), and some scenes are gratuitously harsh and violent. Oh, and the whole serial killer "thing" is getting kind of tired and overused lately, don't you think? (**)
