I thought it was an interesting flick. I hadn't heard of it before seeing it - hadn't seen so much as a preview... which I'm assuming helped my perception of it. They played around a lot with some interesting themes, taken from the books they kept mentioning.
It was definitely marketed wrong. Mentioning Superbad at all in any of the previews was a lie... unless they had said "FROM THE PEOPLE WHO BROUGHT YOU SUPERBAD - COMES A MOVIE THAT IS NOTHING AT ALL LIKE SUPERBAD."
I gave it a few thumbs up for trying with the esoteric intellectual humor. It caught me off guard, that's for sure.
