And I sincerely hope there is no sequel, as the off-to-new-adventures ending indicates. I didn't like that whole little coda that came after the final battle. As I recall, the book ended with Ender being sent home to his family on earth and placed under a sort of suicide watch. The burden of genocide would be heavy enough to make anyone want to end it all. That was the proper ending for that story. Anything else would be cheapening what happened, and that's what the movie did. But up to that point, I did enjoy seeing the story unfold, and I agree that Asa Butterfield made a great Ender Wiggins.
