Most of the first half of the movie was basically a scolding commentary on the antidepressant culture of today's society. Nevertheless, the plot started out to be rather captivating and actually seemed like it might be going someplace interesting. But it went someplace really dumb instead! The "twists" were just too absurd and unbelievable. The climax and ending were not as exciting as they should have been, because the premise was just so baffling. Thumbs down.
