True reasons why this film is rated so low

I will dare say that the film got low ratings primarily from Hollywood. I had a chance to see it in a private screening with Hollywood pros who truly behave like some actors on the set of this film, and they all disliked it immediately. They could not even laugh at any jokes, because they would be laughing at themselves, and that's the last thing they want to do. Hollywood types take themselves too seriously, and hate to be shown what funny and insane creatures they are. Their insanity works only in the world of fantasy and power struggles that they live in and are hooked on.

Same goes for film critics who were thoroughly mocked here, so they were the first to give the film a bad review. Hollywood pros followed, equally dissatisfied with seeing their own mirror images, and the sheeple followed further.

Otherwise, the film is excellent. It could have done without some cheap humor such as those scenes with the dog, but even then, the more biting stuff (John Cusack and his "wellness guide", CZJ on Larry King, Stanley Tucci, etc) more than makes up for it.
