I have so many options depending on what you are into. Grey Gardens (1975) is a must watch, it's totally insane and nonsensical but wildly entertaining. The Jinx (2020) is shocking (true crime-ish), a bit slow at the beginning, but takes insane twists. The King of Kong: A Fistful of Quarters (2007) is something I was not expecting to like, but the people in it are hysterical and interesting.
