Personally I'm pretty distrustful of documentaries. To be entertaining, they usually have to do some amount of narrative manipulation or propagandizing. There are many out there that open a small window into someone's life to make them look extremely evil or heroic while the reality is much more mundane. Some even manipulate interviews with credible people to prove the earth is flat or other nonsense. I love the book Blood Sweat and Pixels and find it very entertaining and inspiring, but I don't trust that it's a nuanced objective look on the 5 stories it covers or that the characters within are as perfect irl as they come off.
