Scientology... a concept in a sci-fi novel that someone realize would make big bucks among celebrities. Because in L. Ron. Hubbard's opinion, "the way to make a million dollars is to start your own religion. (He's the one who wrote Dianetics the book that made Scientology famous.)
So yeah, I don't really view it as a cult, just a bunch of rich people just wanting to be a part of the fun.
