There are no real standout performances in PTU (except for maybe Lam Suet), but the actors all serve the film well in complementing its distinct moonlit mood. The film is pure atmosphere- with lovely cinematography by Milkyway Image regular Cheng Siu Keung, whose camera style is almost as much a trademark of the company as Johnnie To's tight direction.

PTU is slow paced, but involving with its taut dialogue and subtle touches of humor. Though not for everyone, it's the type of film that may work better upon second viewing.
