Most people haven't read Enders Game.
I've read it twice as well as Ender,s Shadow, Xenocide, Children of the Mind and Speaker for the Dead. I already have HIGH expectations...but I know it's only a movie and they can only do so much and most movies do a piss poor job of living up to any expectation let alone a saga like Orson Scott Card's creation. The book was a mind game, not an action drama although I can see how it can turn into a fantastic preeteen drama and action movie...(properly)
