Mongkok Story is decent if unspectacular HK Triad film, definitely from the Young & Dangerous slash-tastic stable rather than the more cerebral side of the genre like Election. Not that that is a bad thing of course.
However when you see Mongkok Story you will probably get a feeling of deja vu as it re-treads familiar ground covered so often in HK cinema.
Edmond Leung plays a young waiter who is seduced by the glamour of being a Triad, especially the local small-time hoodlums who frequent his cafe and their Dailo Roy Cheung. He joins this group but finds the Triad life is not so wonderful after all...
So when his Dailo is killed by the rival gang Edmond thirsts for revenge. So begin the slashing! Overall the film is pretty good stuff though nothing you haven't seen before. Good action and a slightly surprising ending.
