INFERNAL AFFAIRS II is a prequel to the smash-hit movie about undercover operatives and their parallel lives in the Hong Kong police and Triads. This one explores the early lives of the characters played by Tony Leung and Andy Lau in the original, the actors replaced by newcomers Shawn Yue and Edison Chen respectively (Yue and Chen had bit parts in INFERNAL AFFAIRS).
The problem with this prequel is that it feels hurried and unnecessary, lacking almost all the qualities that made the first film so good. Leung and Lau were engaging actors who brought subtle nuances to their roles, but Chen and Yue feel bland and too fresh-faced in comparison. Realising this, the film-makers spend a lot of screen time with rivals Anthony Wong and Eric Tsang instead, but you can't help feel but the plotting in this one is redundant in contrast to the life-or-death stakes of the gripping original.
There's a distinct lack of emotional involvement in the film as the story develops, and although the technical qualities are strong, the twisty-turny plotting isn't. There are the requisite betrayals, executions and bombings, but they have a slightly tired quality to them. This isn't a bad film by any means, but it's one that's easily lost and indistinguishable during a decade in which Johnnie To made seemingly endless variants on similar themes.
