I couldn't bring myself to pay to watch Fahrenheit 9/11.
So I pirated it instead. Except even then I got all of 30 seconds in before I noped out.
I have really enjoyed MM's other documentaries though - Bowling for Columbine and about half of Sicko (I've heard the solutions part is pure bullcrap but the problem statement seemed undeniably true).
So to this day I have no idea why the theory is supposed to be about him - as opposed to e.g. his dad!:-P I am an uneducated heathen, I know...
