Summer Wars (Japan, 2009)

The film tells the story of Kenji, a timid eleventh-grade math genius who is taken to the hometowns of his crush Natsuki, to celebrate her great-grandmother's 90th birthday. However, he is falsely implicated in the hacking of a virtual world by an artificial intelligence. Kenji must repair the damage done to the virtual world and he must find a way to stop the artificial intelligence from causing any further damage.

Hailed as one of the best animated films in recent years, Summers Wars shows pretty fast that it's a force to be reckoned with. It's both a sci-fi inspired adventure with the insanity level on top, and also a subtle, quiet drama that excels in how to show human emotions. 

Directed by Mamoru Hosoda, who also made the brilliant The Girl Who Leapt Through Time.

Genre: Adventure/Sci-Fi
