Personally, I was very disappointed. The trailers implied something that wasn't true, that she had some sort of special powers. She didn't. She was just a rebel and able to control her fears. I kept waiting for something to happen to jazz it up and nothing did. It just was a real letdown for both me and my husband.
My husband saw Ender's Game, also said it was a disappointment to him. And he's a real movie buff that it takes a real clunker to turn him off.
Of course, I'm not much of a movie buff in general. I can go forever without watching one because more often than not, I'm disappointed.
