The good stuff
A very solid sequel that shuffles things around (with an entirely new cast for one), but offers the same thrills as the first film. In other words, expect undercover police work and tight action scenes. Koo, Yam and Leung are on a roll here, the film looks slick and the pacing is perfect. Not a future classic, but extremely entertaining.
Worthy but flawed
Vintage Jing Wong. It feels a lot like a film I've already seen, then again Wong made a bunch of similar films around that time. The quality of these films is rather low, but the pacing is nice, the atmosphere is extremely light-hearted and while far from great, they make for an amusing 90 minutes. Decent filler.
Regardless of all the big names involved, Fascinating Affairs is a pretty rushed and flat hotchpotch of genres that never really finds its footing. Loud, poorly acted, lazily directed and often aimless, it's a film that seemed confident that star power would be enough to attract people. Poor filler, only for true completists.
