At this point in history, if you know anything about Scientology but you think it's not as bad as it has been painted, you are a good candidate to become a Scientologist. That's not a recommendation; oh my, no. I'm warning you that you're vulnerable.
I'm not going to watch the documentary or read Wright's book: I very much doubt I would learn anything new. If you know nothing about the organization, though, you should probably watch or read: forewarned is forearmed, and you definitely want to be forearmed against Scientology.
