Just watched the documentary "The Smashing Machine" about Mark Kerr, a former collegiate wrestling champion and full-contact fighter. I think this film has been mentioned before on EF, but I just wanted to recommend it again as a very well made documentary about a very interesting man. What I liked about this film is that it shows a lot of the personal pressures facing someone who chooses the life of a professional fighter. Mark Kerr, despite the immediate impression he gives as a beast of a fighter, is subject to the same frailties of the human condition that we all are.
I give The Smashing Machine 4 and a half stars out of 5 as a documentary.
