Was it the fact that Chow Yun-Fat came back as his own twin? ;D Yes, yes, the film is silly, but it's silly fun. If you watch it under the right circumstances it's as great as anything Woo ever made. It's only a shell to delivery killer action sequences and once you take that into consideration, it makes it easier to just sit back and laugh at it. And indeed, the mansion shootout is one of Woo's best gun battles and easily some of his bloodiest work.
