My wife and I thought this was an excellent movie. We hope there will be a follow-up, maybe Ender's Shadow, for those familiar with Orson Scott Card's work. Not as much zero-gravity foolishness as Gravity, but I think that is a plus! I particularly enjoyed watching the character of Ender mature as he progresses through the movie. Harrison Ford's character was pretty much an unsympathetic one-dimensional militarist; I thought his character less interesting than several of the children.
