via POV - The United States of Documentaries| PBS
Documentaries bring us closer to the world. We get to go places we normally can’t, and learn about fascinating people and important issues that might otherwise be ignored. But just how comprehensive is our understanding of our own country, based on the documentaries we see?
The United States of Documentaries is a representation of the best documentaries each state of [the USA] has produced. When I say produced, I mean the main story and subject are set in that state. And when I say best, it could either be that the film itself is great, or that its connection to the state is the most unique or telling.
The full state by state list is here. (Thank you sav_.)
