This movie started shooting in 1982(look at the letter written by Damian Lau to Leung Kar Yan, it's dated to 1982), but probably the production had to have been cut short because Golden harvest may have been saving their funds for American coproductions at the time. Nevertheless, it's a movie you either love or hate. Watch the first 40 minutes of this for some quality HK filmmaking, the last half hours just disintegrates. Leung shoots one of the best examples of the European giallo in the scenes where Chan Wai Man stalks Pat Ha. The lighting, use of the thunderstorm, careful camera work, and editing in those scenes create a nice range of contrast. It's so beautifully shot and Chan Wai Man is just perfect as the psychotic killer. Leung kar yan's fight with Chan Wai man is brutal, as Chan has never been captured on screen this powerfully before, as most of his punches and kicks are full contact. There is some nifty Wing Chung kung fu techniques that Leung surprises Chan with. Besides that, the music score is excellent, and Philip Ko and Chang Yi are in there prime. The loud kickboxing sound effects used by Sammo Hung and Jackie Chan at the time are used to a great effect here, intensifying the fight scenes. The is a stylish movie, but it ends too preditctably and quickly. If the end would have been as stylish and calculating as the beginning, this would have been a classic HK action drama. ***1/2(for the first 40 minutes)/*****
