I love a good documentary! Here's some of my favs.
An Honest Liar - All about James Randi and how he exposed so many fakes and frauds in areas like psychics and faith healers (He outed Peter Popoff). He also pulled a couple of great hoaxes including fooling scientists into believe psychic powers are real, and making hundreds of thousands of people believe in a fake faith healer he created.
The Great Hack - An in depth look at how the Cambridge Analitica scandal came to be and what it really meant/means for our privacy (and what that actually means as a human these days).
Dealt - A documentary on Richard Turner, he's a blind "card mechanic". Basically, he can do things with a deck of cards you would never think were possible, and he does it better than anybody in the world, despite not being able to see (oh, he's also a fifth degree blackbelt, yeah...)
Enron: The Smartest Guys in the Room - A great look into how the Enron scandal went down. Culture High- One of the best weed docs that looks at the business of cannabis and the war on drugs.
