Who has watched the documentary ' The Smashing Machine' with Mark Kerr? I've only just watched it today. I knew Kerr was nuts but that documentary is crazy. He was a walking candidate for a heart attack. Some awesome behind the scenes stuff as well, one of the best documentaries I've seen.

Are there any similar ones worth watching? Most of the others I've watched are nowhere near to the bone or as honest or open as that one.
