This is truly the greatest action comedy I have ever seen. Unlike most action comedies, it can have a huge load of action without detracting from the comedy.
The only bad thing I can think of is that the movie seemed to be kind of short. I'm sure that if the producers really tried they could make this movie longer.
Chan did a very good job acting. Best performance as a police officer I've seen in a long time. He also had a few funny lines here and there. Of course, Tucker was my favorite part of the movie. He was always saying the wrong things at the wrong time. Normally, I don't find that kind of stuff funny, but fast talking Chris made me a believer.
For a comedy, this movie had a decent amount of suspense. When the two cops are trying to rescue the little girl, I can honestly say it had my heart pumping (Even though I knew what was going to happen. I'll admit that)
The villains did a good job too. I particularly liked Ken Leung's performance as the secondary villain. He seemed like the most menacing character in the story. His final battle with Tucker.
All in all, this movie is fantastic. There weren't many great movies in the 90's (Watch "Nostalgia Critic" and "Nostalgia Chick" if you don't believe me), but this one is truly elite.
