I have debated going to see it. I enjoyed the books, but I didn't find them all that great. And I've had friends tell me

"Don't go see it if you really, really liked the books, 'cause while not bad, they don't follow the books closely enough."

and others say

"Don't go see it unless you really, really know the books 'cause they make all kinds of references you won't get."

I'll probably wait until it comes out on DVD.
