I don't undestand why they decided to make a movie adaptation out of the book instead of the controversy surrounding its publication. That would have been far more interesting.
This movie is the poor man's Xavier Dolan film - and even his "artsy" shots are obnoxious enough. I assume they expected this movie to be an award winning project: nudity, check; tears, check; redemption arc, check; artsy shots out of nowhere, check. They even throw a couple of scientologists to the mix!
Overall its plot is as basic and predictable as you would expect it to be had it been made during the 90s.
