Comments: Fifty years ago an alien race came to Earth and was narrowly defeated. The International Fleet has been preparing for a subsequent war ever since. They found that children made the best leaders because of their quickness to learn and adapt. This film centers around one youngster, the third-born--appropriately nicknamed Ender--as he is prepared to attack the enemy.
This is a very good film. The message is clear, though not clear cut. It also confronts the ethics of children in combat. Highly recommended.
I read the book afterwards. Here are my comments. The film follows the novel well, if in a simplified manner. The ending is tailored to garner the contemporary audience's approval. I would have preferred the novel's ending, since it is more powerful. Well done, though!
