I think this is the big ethnographic list that looked interesting to me. I remembered it as pure ethnographic but that's not that case.

By the way here's some moaning that ethnography has been very hurtful to its subjects.

<For indigenous peoples the camera is a dangerous weapon, one that has been wielded against us since the device’s inception. Anthropology's obsession with preserving images of our “vanishing” cultures, through ethnographic films or archives filled with boxes of our ancestors' remains, has long been a tool used to colonize and oppress indigenous peoples.
I am skeptical about this screening night because it sounds like the presenters poisoned the well. I agree it would be aggravating to have one's historic culture mischaracterized by outsiders. But these guys seem concerned with wallowing in victimhood, primarily defining themselves in terms of the evil ethnographers instead of focusing on a positive counternarrative.
