Following the trajectories of three of boxing’s greatest fighters—Evander Holyfield, Mike Tyson, and Bernard Hopkins—Champs is an extremely concise overview of boxing. You can already take deeper dives into these boxers' careers (especially Tyson’s, and I highly recommend a closer consideration of Tyson) in more focused documentaries, but Champs is crisply edited and astute, and features the delightful addition of Mary J. Blige as one of its talking heads. Consider it an excellent introduction to a deeply interesting, and often very dark, part of America’s sports culture. by Marjorie Skinner
