This follow-up to "Police Story 3" is not nearly as good as its predecessor, despite having the same director (Stanley Tong). Although it is supposed to be a starring vehicle for Michelle Yeoh, she has surprisingly little to do. She gets about 3 fight scenes in the entire film (she does show her awesome flexibility in those at least), and is absent during many of the climactic set-pieces! The whole movie seems to favor (dryly directed) gunplay over martial arts, and although there are some spectacular stunts, they are pretty much par for the course for Hong Kong cinema. The most interesting aspect of the movie is the relationship between Yeoh and the bad guy who sincerely loves her, but the ending resolves that in a rather too-convenient way. Jackie Chan has a 2-minute scene that is so outrageously silly you can't help but laugh; also watch out for a brief appearance by Yukari Oshima during the opening action sequence. (**)
