So HBO decided to take Scientology down a couple pegs with their documentary Going Clear: Scientology and the Prison of Belief . Pretty much everyone knew they were a cult who believed in a funny space alien (except for the bottom rung cult-members) and were started by a science-fiction novelist. I'm sure most people didn't know about the other shenanigans they've been up to over the decades. Now, I don't mean to cast aspersions on those kooky Mormons, but Scientology makes them look downright rational about their space fantasies!
