Even if Tom Cruise had some good points against psychiatry, he is coming off a some sort of nut case. What I understand about Scientology, they are no better than any other cult.
Scientology is a brand of wacky that makes most JW doctrine look sane, well reasoned, and perfectly legitimate. One of the fundamental tennants of Scientology is that psychology is nothing more than a pseudo science, and there is absolutely nothing that can or should be treated by ANY branch of psychiatric medicine. Of course, one of the other fundamental tennants of Scientology is that long ago a man from another planet gathered up all the negative inhabitants of his world into giant nets, brought them to earth and placed them on two volcanos and then detonated each group with hydrogen bombs rendering them into atmosphere dwelling souls called 'thetans'.
The problem with listening to anyone who espouses the ideology of a high-control organization is that even if some of what they say actually seems to make sense, it's very difficult to overlook the fact that absolute craziness is being asserted as fact right alongside the things that just may be true. It's like saying 'This book on Egyptian Architecture has some wonderful historical references and fascinating information--if you ignore that the central theme of the book is how an alien race from the planet Xantho 5 were the original builders of the civilization."
