I thought that article was poor. The author (Alyssa Rosenberg) basically says the film mocks Scientology and Scientologists and that if people were really serious about helping Scientologists leave the cult they would be more respectful of them and their beliefs and that our empathy would help them leave.
I LOLed. Ms. Rosenberg apparently has never met any actual Scientologists.
She needs to clear the word 'mock'.
