You should check out Woo's earlier work. Anything he did in Hong Kong from Heroes Shed No Tears to Hard Boiled is worth owning. His films are melodramatic and it takes a special kind of person to get into them, but most people who dig on cult flicks tend to at least like The Killer and Hard Boiled. His Hollywood work has been utter crap, I didn't even like Face/Off which a lot of people seem to dig.
I'm hoping Paycheck will let him catch his footing again. It may be being far too optimistic, but I'm hoping he can create a new name for himself, because I doubt he'll ever rightfully return to the Heroic Bloodshed genre. Anyway, I'm rambling I think. :)
