Does anyone have a good South Africa documentary?

I watched Mandela: Son of Africa, Father of a Nation over the weekend and was kinda bummed by it. I was hoping for more insight into the revolution: how the revolutionaries made decisions, how and who kept the movement alive while he was in prison, what was the theoretical basis for their actions. Instead, it was more of an encyclopedic timeline summary of events, as if things just happened for no reason. Then of course Mandela’s election is presented as perhaps the most important result of the liberation struggle, not yknow the ending of apartheid.

Can anyone suggest a documentary on the anti-apartheid struggle in South Africa that focuses on the revolutionary organization efforts?
