This documentary is well done … interesting and informative. I found it particularly compelling in light of current events. So much of what they say about Scientology is also true of other groups hostile to Judaeo-Christianity.
My only caveat in recommending it is that the film maker appears to have a bit of an animus against ALL religions. Note how the title says “Scientology and the prison of belief” and not “Scientology: A prison of cult” which IMHO would have been more accurate.
