I can't improve on Mr. Blue's review below; he's spot on.

This is a movie with a plot that's familiar but competent, acting that's adequate but not award-winning (I thought Jackie Cheung overdid his despair in a couple scenes), writing that's tight but not flawless (e.g. Wu Chien Lien's movie brother, Roy Cheung, tells Jackie that their parents died when Chien Lien was very young, but later she makes reference to something her mother said when she had reached puberty).

Dissected, a lot of the elements seem average, but as a whole it rises. It's not a great movie, not a must-see movie, but one that is rewarding and sustains multiple viewings. I recommend you pick up a copy before it disappears forever (I had to get a vcd, couldn't find it in dvd).
