Summer Wars (2009)

Kenji is your typical teenage misfit. He�s good at math, bad with girls, and spends most of his time out hanging out in the all-powerful online community known as OZ. His second life is the only life he has � until the girl of his dreams, Natsuki, hijacks him for a starring role as a fake fianc� at her family reunion. Things only get stranger from there. A late-night email containing a cryptic mathematic riddle leads to the unleashing of a rogue AI intent on using the virtual world of OZ to destroy the real world. As Armageddon looms on the horizon, Kenji and his new �family� set aside their differences and band together to save the worlds they inhabit in this “near-perfect blend of social satire and science fiction.”
