Celebrating the diversity of filmmaking in and about both Africa and the diaspora, the African Diaspora Film Festival has been a city institution for nearly two decades now. Much to our chagrin, though, we have a tendency to miss it. (It's held in late November and early December, right in the heart of awards-bait movie-screening season.)

We've waded through the selection and come up with five favorites. Here is the best of the Best of the African Diaspora Film Festival.
