Loved it. Typical late 80s Hong Kong style but the done superbly well. This is a film that helped put down a lot of rots in films like Infernal Affairs (The Departed) and Reservoir Dogs, but for me, it supercedes them. It actually also happens to be quite tragic in its way. Ko-Chow is just too cool for this earth ultimately.
It's definitely worth a watch and if you don't think so, I think you miss the point of films in general, and I pity you.
