Watching on TMC right now

So I was flipping through the channels and started watching. I've only been watching for about 15-20 minutes, but already the director is extremely annoying. He's nodding his head constantly. Why is he even in the interview shots? Most documentaries do the interview portions while showing only the interviewee. Seriously, put your ego aside and focus on what's important. Seeing your fat head in every shot does not contribute to the story.
