I just discovered the Super Hero Beat Down series and this guy REALLY knows how to do a cool fight scene. More importantly, he can make things look cool on a TV show's budget.
It didn't look like he had any credits for anything other than low budget fan films to be honest. Personally I would hope they go with someone with more experience.
I'm not familiar with that name but since iron fist is getting a tv series not a movie (at this point at least) I think marvel will be looking for a show runner more than a director
