I try to only say good things about other people's creative works. If I don't care for something, I try to let it slide without comment.
But this is, without a doubt, one of the most reprehensible films ever made.
I'm a video editor. I know how easy it is to fool people with stunts like this. This clown spent a lot of time going around the country, goading people into reacting to him under false pretenses. He then took the gigantic amount of footage and cherry-picked that which showed people at their worst.
Two types of people like this movie: the gullible and sociopaths. Even if you claim to like it "ironically" (under the popular misuse of the word), it calls your opinions on just about everything else into question.
