There are a number of documentaries about this having accumulated since the 60s, but the phenomenon is that each new documentary reveals new more shocking facts about the business and its mentality than the previous ones, apparently because the material is still accumulating. There is very much important data from earlier documentaries missing here, many key persons are left out of the picture, which nevertheless is completed by the new ones appearing, corroborating all previous testimonies. It's a vitally important documentary, most of all because in the world society we are living in today so many, if not the majority of people, are not aware that it is an age of brainwash, and they still haven't learned to protect themselves against it. What you marvel at in this documentary, which many of the participants honestly do, is that they keep swallowing the racket for years before they can bring themselves to accept that they have been swindled, in most cases of their lives, which they don't realize until their lives are lost or completely devastated. In an effort to concentrate on the good things in Scientology I wrote an article some years back where I posed the open question - what went wrong? Apparently everything went wrong from the beginning, the founder having no self-criticism and no objective distance to what he was doing, but simply himself first of all falling a victim to the delusions of his own science fiction fantasies. Of course, there must be something good in Scientology, there must be a corn of truth in it somewhere, but whatever once was good and even of some worthwhile philosophical common sense and rational wisdom was flooded by the bolting derailing vicious circle of greed fueled by unrestricted paranoia, the constant validation of which seems to be the very substance and force of the organization.
