This is a fun movie about a sport I love and an iconic American. The importance of Billie Jean King transcends sport (and she is arguably the one of the most important athletes of the 20th century). Her story is interesting, daring and entertaining. The Battle of the Sexes was obviously a big and important event, but the US Open awarded equal prize money the same year to the men's and women's tournaments apparently outside of that context and it would have been useful to include that more directly. A little less of their personal lives would have been fine too. It was kind of long, otherwise they could have included more tennis politics. The movie is quite funny and it boasts a big cast of comedians, even in small roles like Fred Armisen, who has a couple lines and then sits quietly.
