I guess I'm more of a passive viewer. I rarely pay attention to the fight scene. There are a few that catches my attention because it really looks more like a dance choreography than a fight. The only time I realized how hard choreographing or even imagining how a fight scene should be was when I had to write a fiction story with a fight scene in it. Of course, I haven't been involved in a lot of brawls so there's nothing much to work with in my imagination.
