Con todo y que Asa Butterfield tiene una buena actuación, y que los efectos visuales son impresionantes, dicho aspecto, desafortunadamente, acaba estando por encima de una idea interesante: los niños usados como carne de cañón, en una guerra espacial-futurista.
In a world at war, the main character delivers a dissenting perspective about concepts like enemy or lack of communication between different reality - almost exclusively compressed in an intense surprise ending. Double surprise, considering the homophobic tradition of OSC, screenwriter and author of the novel.
While it is very faithful to the book (and uses a TON of dialogue from it), this story is simply not meant for the big screen. The tension in the book came from Ender's inner thoughts/psychology, all of which you can't get in a film without boring voice-overs. On the screen, we have an enemy that we never see; when they fight the enemy, there is no physical threat to any of the characters. Oh well
