Slightly above Average HK crime thriller which is thoroughly watchable with a mix of comedy and cop/action, though there's lack of the latter. Most of the plot is taken up by the scheme to bring down the gang leader, and of course, some romance. One of the reasons this is decent film is helped by the performances by Cherie Chung, who is excellent as a drug addict informer, and the likeable Andy Lau. Their chemistry and interactions are quite good. The ending is quite sad, contrasting greatly with the mainly breezy/comic feel.
