Good movie with a message

Outside the well-chosen actors and the very good effects, shows Ender's Game of the dangerous thoughts and consequences of a "preventive war". Another aspect of the story is the exercise of power and its abuse against children. A twisted power of ideals, which often make parents own.
Many critics believe that Enders Game more of a child's or teenager's film. I see absolutely different. Certainly the children are the main actors and the initial development of friendship and success is somewhat reminiscent of Harry Potter. Nevertheless, the background of the history of another, and finally, the story changed in a very serious film. I hope there is a sequel!
