I liked the film. Torn apart between two of the best films of its genre this year. This and Knocked Up but Knocked Up scores more points thanks to Heigl. Jonah Hill just bloody reminded me of Eric Cartman. Couple of scenes stood out:

1) Drawing penis. The kinds of penises that he draws are beyond imagination.
2) Buying liquor - he imagines the happy endings that he will have LOL

But more importantly I thought it was very thoughtful. I mean you watch American Pie and you think it's a bunch of crap but you watch this and you think, awwww, we could all have been in that position. Wanting to be a beautiful girl's mistake only to realize that the girls like them for who they are (when sober).
