In writer/director Gavin Hood's sci-fi adventure Ender's Game, our titular hero (Asa Butterfield) is a 12-year-old who's bullied both at school and at home, whose gestating anger leads to frequent violent outbursts, and whose frighteningly focused skills at computer-simulated war games not only earn him the respect of his peers but, eventually, the grateful thanks of every man, woman, and child on the planet. It is, in short, a Revenge of the Nerd fable to out-Carrie Carrie, and about the strongest argument for 24/7 video-game compulsion that any young game-hound could wish for. Just keep playing, you can hear the movie whispering to its console-obsessed demographic. One of these days, you'll show 'em. You'll show 'em all.
