Movie Info

Kenji is a teenage math prodigy recruited by his secret crush Natsuki for the ultimate summer job - passing himself off as Natsuki's boyfriend for four days during her grandmother's 90th birthday celebration. But when Kenji solves a 2,056 digit math riddle sent to his cell phone, he unwittingly breaches the security barricade protecting Oz, a globe-spanning virtual world where millions of people and governments interact through their avatars, handling everything from online shopping and traffic control to national defense and nuclear launch codes. Now a malicious AI program called the Love Machine is hijacking Oz accounts, growing exponentially more powerful and sowing chaos and destruction in its wake. (c) GKids

  • Far from resorting to easy, reactionary technophobia, Hosoda shows Japan's age-old traditions being upheld throughout different generations, with the beautifully realised digital community of OZ proving as much the solution as the problem.

  • The filmmakers can't keep the strands of their clumsy plot straight, but they create brilliant images and manipulate them with blithe abandon.

  • An enjoyably trippy Japanese animated feature from director Mamoru Hosoda, Summer Wars combines real-world drama (school crushes, testy relatives) with virtual-world dramatics.

  • The story's been done better (and balder) in Die Hard With A Vengeance

  • The relationship between Kenji and Natsuki unfolds as blandly as a Debra Messing rom-com.

  • It's a sugar rush of candy-colored images, a beautifully drawn tale of family tradition and a bracing brain tonic about the Internet's charms and vulnerabilities.

    A rogue artificial intelligence wrecks havoc on "Oz," an omnipresent virtual reality network of the near future, seizing control of most of the world's computers; a young math genius is the only hope to save the infrastructure. Decent juvenilia with outstanding psychedelic animations in the nonsensical but beautiful cyberspace battle scenes.

    In "Summer Wars," Kenji works as a part-time programmer with his friend Sakuma for OZ, a worldwide operating system/social network. He takes a break when he is invited by Natsuki to attend her great-grandmother's 90th birthday party. But he is horrified when she tries to pass him off as her fiance.(On the plus side, he turns an adorable shade of red.) That's not the worst thing that happens to him that weekend as OZ is corrupted and crashed by an outside source that is traced to him. So, he does the one thing he is supposed to when confronted by a computer problem which is to find the nearest kid to explain it to him. Even with its share of banalities and contrivances, "Summer Wars" is still an enjoyable animated film. While the sequences inside OZ are much more impressive than the ones set in the real world(and it would have been fun to have explored OZ a little more), the emotional core of the film is the extended Jinnouchi family that has more than its share of members employed in public service with the movie definitely in favor of collective action. In this way, you could say that Japan is not only a country that respects its traditions(as one family member recounts the family's military battles) but one that also looks towards the future. Just don't keep all of your eggs in one basket.

    Japanese animation with a boy-girl romance, a wacky extended family , virtual reality all mixed up into one. I usually find these kind of plots a bit tedious, and I lazily watched it in an American dub too, which rarely does these kind of films any favours. But it definitely had a charm, a colourful alternative reality and some nice little human interactions before the big-chase-to-save-the-world-before-it-blows-up kicks in for the action junkies. . <img src="">

    From the people who brought us The girl who lept through time, which i loved, another slice of beautiful animation, and at its core, a relevent story of todays age. the perils of online living, here the world is connected to one online system, everything is on there, and when a code is broken unknowingly, it allows a hacker to mess with the system and cause destruction at highest order if not stopped, all this done through online consumers and acounts. certainly a warning of todays age, while in the system, avatars take control and the fight continues. wonderful animation, and engageing story, it makes sence when watched, as the hacked system causes mayhem on outside world, while digital world inside is very sci fi. a entertaining blend of anime
