The list of things that Battle of the Sexes isn’t really about is one longer than an Isner/Mahut game. For one, it’s not really about tennis. It’s also, in a funny way, not really about the battle or even the sexes. From directing duo Valerie Faris and Jonathan Dayton, here is a film about lost souls on the margins of society and how they deal with the rough road that life has thrown their way. Fundamentally, this is a film about equality for all sectors of society and a reminder of just how far from over the struggle really is.
