"I attacked him...in front of these old decrepit white women...I just attacked him and stomped him," shares Mike Tyson in Tyson, James Toback's weirdly sympathetic documentary, told entirely in the boxer's own words. Sure, the guy Tyson "stomped" is Don King. But the matter-of-fact way Tyson describes publicly beating a man before a host of elderly onlookers as if it's a perfectly normal thing to have done, is equal parts disturbing and engrossing. It's unclear whether Toback intends the film as a Tyson exoneration, or simply a fascinating character study of a troubled, complicated, monstrous man. It feels like both.
