Dude, how can you judge a book by it's movie?
Well, I'd assume that at least the basic outline of the story and characters would be the same, that would be enough for me.
I am not saying that the books aren't good, since I havent read them I cannot comment, but the basic idea doesn't appeal to me.
I'm getting mine from Amazon today.
Pity you don't live in the UK, Kwik Save are selling it for 5.99.
