"Virunga"
Damn!
In the Eastern Congo is a wildlife park that has survived for 100 years. Because of the Rwandan Genocide, and the Congolese civil war, it's now caught between the M23 Rebels in western Uganda, corrupt Congolese officials and a shady Oil company who will bribe their way to fat profits to mine the minerals and oil the park sits on, wildlife be damned.
It reads like every bad film about Africa for the last 50 years. Trouble is that it's a documentary.

This film is about the Park Rangers who must defend the park from all those wanting to destroy what it stands for, and their efforts trying to preserve the remaining 800 endangered Mountain Gorillas left in the park against Big Oil, corruption and poachers.
Seeing an adolescent gorilla laughing their face off at being tickled changed them for me, from animals to 'people'. I hope it does for you too. And seeing people carry off a male silverback after it had been killed by poachers was just sad, and amazing. I knew they were big, but holy shit!
There is a trailer you can watch here:
