I saw The Way, Way Back yesterday, and I was struck by how white it was. Except for Maya Rudolph and a few background characters, the movie had no POCs.
That got me thinking - the whole coming-of-age genre (especially the "summer that changed my life" subgenre) is a very white one. One of the few exceptions I can think of is Boyz N' The Hood, but even that is more about gang violence than the joys and pains of being a teenager.
Can you think of any other good ones?
