This is a fine movie. One downside is if you read the book before it's gonna be underwhelming. In the book we had a full 25% of backstory and why he decided to go to the hospital. Here the movie starts with him already there. (not talking about the prologue that really is just a Hollywood tickbox). In the first minutes, we find out that he is 16 should've been 15 why the change but ok... then someone asks his age. Why make him tell us his age when we find it out from dialogue anyway? [spoiler] His character feels like the point of view character, not the main one. Zach Galifianakis's character that I really don't remember from the book that much (except de sweater scene) stole the show. Noelle's face looks scratched by a cat not like she did it herself with a pair of rusty scissors. That was really disappointing 'cause she describes them like it would stop any kind of future job offer. Nia looks like a hallucination. I mean they really put alien music when they zoomed in on her boobs. She totally looks like a sex addict in the movie. She had sleeping with him on a list. At least in the book, he kissed her. Then he says he loves her ???? This brings us to the stupid love triangle, cause of course Noelle is there. Zack Galifianakis, saves it again, with the brilliant delivery of the "Yo mamma joke". He talked with Noelle twice and it wasn't as deep as it was in the book either. Did they just monologue the conversation? Sure, cause we didn't need any build-up for the relationship. And that one performance of Under Pressure o_o. [/spoiler]
