Anthony Wong Chau San and Michael F. Wong star in this truly excellent cop movie co-directed by Gordon Chan and Dante Lam. Michael plays the straight shooter with clear sense of morals who gets reassigned to a new beat in Tsimshatsui where he teams up with Anthony, who's been living comfortably in that great zone where gambling/hookers and the friendly attentions of the neighborhood triads don'r seem quite as bad. For most of the movie, we have a well-written character study, dominated by Anthony Wong who gives a career performance. The supporting players (Kathy Chow, Sam Lee, Roy cheung) are all excellent, and the movie manages to generate interest in these characters without ever becoming predictable or resorting to conventions. The final reel turns into a revenge-driven action setpiece set against a quirky music soundtrack reminiscent of Dante Lam's later Jiang Hu: The Triad Zone (and I wouldn't be surpised to see Quentin Tarantino rip it off in his new movie). Definitely the best HK movie I've seen in a while. Highly satisfying.
