Matthew Sweet is joined by art critic and boxer Lynda Nead to review the much-anticipated documentary about the life of Mike Tyson. Tyson grew up in New York amid crime and violence, but after being spotted by the famous boxing coach Cus D'Amato he went on to become arguably the most feared fighter of his generation. But after his trainer's death, his career spiralled into shame and disgrace, culminating in his biting off a chunk of an opponent's ear.
