Steven Spielberg of combat sports short documentaries might be hyperbole.
In any case, the guy makes amazing short documentaries and pieces covering combat sports (and he chooses music just like a teammate of mine plays on our way back from tournaments and we're all banged up).
I can relate to the idea of simply wanting to showcasing your skills. I don't particularly like fighting. When I go to an MMA event, and I see how many people are simply there to see someone get hurt, it's disconcerting. Ultimately, I fought to know in my heart that I could do the things I practice and do in training.
