Joe,
I'm curious why you label these clips as "good". What characteristics make them good, in your opinion?
The first one looks less-than-real to me. For some reason it looks staged. Everything from the camera angle, to the crowd, the "fight" itself looks like something from a grade-B movie. The nice big telegraphed haymaker and all doesn't give me a sense that this was spontaneous confrontation.
The second one looks like the guy has some skills, but his "opponent" is just passively taking a beating. Even when he attacks it seems as if he's moving in a way that has already been perscribed to achieve the desired outcome.
