PBS Frontline probably makes the most consistently depressing documentaries. They also somehow get consistently amazing access to war zones. They did an episode on Yemen recently, and they have one on Mosul coming up. I find these extremely disturbing – if the measure of success in fighting terrorism were taken to be the cost in civilian lives and human rights, I am not sure any of these wars would be worth it. Humanitarian war is an oxymoron – if our political leaders are waging war to achieve geopolitical objectives with little regard to human rights, the people need to understand how horrific that is and try to come to terms with it. These documentaries do a pretty good job at that.
