I love Showdown, but it is flawed. Very entertaining and very "eighties" (even though it came out in the nineties. It's a fun, dumb, pop corn movie.
Showdown could have been a franchise, like a cheap-o Lethal Weapon. They could still make a sequal, just get Marc Dacascos to replace Brandon Lee (a always), or playing the character's brother or something.
Bridge of dragons is more of a missed opportunity for me, I have a hard time getting in to that movie. It is, despite all it's fights, strangely boring to watch. And Florentine's style is like a fanboy hommage to Hong Kong cinema, it never quite gets there.
