Cute. Very Cute. I haven’t read the entire book so I don’t know how accurate it was but all the actors looked under the age of 18. Although there was action, it seemed too fast paced. Within a week (or so it seemed), Ender had jumped to commander and then he just escaped from his duties to save an alien race. I don’t know… They could have done better. But I’d advise seeing it for yourself to make that decision. And IMAX? It’s not going to make that much of a difference.
