The Internet is messed up - everywhere. And Oz, a mega-site that combines social networking with e-commerce with entertainment and the chance to order pizza, has been corrupted.
It's a World Wide Web catastrophe, but luckily there's a teenage math brainiac named Kenji who may be able to save the day, if only he can get his avatar to face off with the towering cyber-villain Love Machine.
An enjoyably trippy Japanese animated feature from director Mamoru Hosoda, Summer Wars combines real-world drama (school crushes, testy relatives) with virtual-world dramatics. There are scenes in Ueda, the Japanese city where Kenji and his would-be girlfriend, Natsuki, go to visit her family, that have the lovely, painterly quality of a Miyazaki cartoon.
