28. 'Unmatched' (Dir. Lisa Lax and Nancy Stern Winters)
Martina Navratilova and Chris Evert played each other in 80 professional tennis matches, with Navratilova finishing with only a slight advantage in wins. But Unmatched is more about their personal lives off the court, where Evert's turbulent romances and Navratilova's coming out as a lesbian put them both through trials and brought them closer together. It's a sweet study of how competitors forge bonds over time, and how there's no friend like a rival.
