What are you worried the movie will get wrong? What is the most beloved aspect of it for you?
And in case it wasn't obvious, the thread will be for people who have read it and therefore be spoilers up one side and down the other. (I mean, unless everyone is too busy for armchair movie critiquing this morning.)
edit I ask this because my friends list has been peppered with posts that are, essentially "please don't screw this up".
