This documentary is basically an excuse for the lack of a human being that John McEnroe was. It wants you to understand what a tortured crumb of a person he was, so in the light of history, McEnroe can seem like he is less of a turd.
Having grown up during his era of rudeness and nastiness to everyone that he felt was under him, I can say this guy is despicable. McEnroe kicked every little person all the way to the top, and then kicked them some more. He was and is a vile human being, and he has spent his retirement years trying to retroactively clean up his reputation.
McEnroe had no love, compassion, or respect for anyone. This documentary should have interviewed the hundreds of people that he humiliated and abused during his career and afterwards. Where are their insights into the sub-human that is John McEnroe??
