2. Unforgivable Blackness: The Rise and Fall of Jack Johnson
From Ken Burns, the man who practically invented the modern documentary - his 'Civil War' and 'Baseball' are some of the greatest documentary series ever made. A weighty work in two parts, it's well worth taking the time to appreciate this masterwork which charts the fascinating life of the first black heavyweight champion on the world.
