GREAT movie, but a little contrived (spoilers)
As a person who thinks the honor is being completely sucked out of martial arts (yeah, thanks for that, MMA) I thought it was great to see a movie about a guy who would do anything to restore respect to the broken system that he loves so much. I thought that aspect of the film was amazing. That being said, there were certain plot elements that I just didn't buy off on, well maybe just one--the cop suicide. That felt really forced and unrealistic. Other than that, it was a great movie.
You'd feel cocky too if you were full of myself.
