We know movies aren't real, but we want to see how the illusion was built. When The Disaster Artist (or the documentary The Master of Disaster ) shows Tommy Wiseau throwing a football terribly, we feel superior. We understand the craft because we see the failure.

Consider Britney vs. Spears (Netflix). This documentary did not just recount the pop star’s rise; it acted as a piece of investigative journalism into the conservatorship. The director, Erin Lee Carr, became a character in the film, making phone calls and digging through court documents. Similarly, Framing Britney Spears (The New York Times) changed legal policy. The documentary didn't just entertain; it agitated.
