OZ, a virtual world connected to the internet, has become extremely popular worldwide as a spot for people to engage in a large variety of activities, such as playing sports or shopping, through avatars created and customized by the user. OZ also possesses a near impenetrable security due to its strong encryption, ensuring that any personal data transmitted through the networks will be kept safe in order to protect those who use it. Because of its convenient applications, the majority of society has become highly dependent on the simulated reality, even going as far as entrusting the system with bringing back the unmanned asteroid explorer, Arawashi.

Kenji Koiso is a 17-year-old math genius and part-time OZ moderator who is invited by his crush Natsuki Shinohara on a summer trip. But unbeknownst to him, this adventure requires him to act as her fiancé. Shortly after arriving at Natsuki's family's estate, which is preparing for her great-grandmother's 90th birthday, he receives a strange, coded message on his cell phone from an unknown sender who challenges him to solve it. Kenji is able to crack the code, but little does he know that his math expertise has just put Earth in great danger.

Director Hosoda Mamoru chose Ueda in Nagano Prefecture as the setting for Summer Wars because of its proximity to his birthplace. The film earned over 18 million USD in worldwide box offices and won the Japanese Academy Award for Animation of the Year in 2010. Hosoda became only the second Japanese director (after Miyazaki Hayao) to be nominated for an Annie Award for his work on Summer Wars.

Summer Wars was the first Japanese animated movie to be nominated for the Golden Leopard Award at the Locarno International Film Festival in Switzerland in 2009. The movie also won the Anaheim International Film Festival's Audience Award for Best Animated Feature and the Animation Division Grand Prize at the 13th Japan Media Arts Festival.

As far as family entertainment goes anime is rarely high on the agenda, especially given the numerous offerings from Disney, Dreamworks, and other such movie studios. Generally their features appeal to children and adults alike, and in order to compete with them Japanese animation studios have had to shake off their habitual approach and focus on making films that are more accessible to Western markets. The undisputed king of this is Miyazaki Hayao, however there have been several challengers to his throne, the latest being Hosoda Mamoru.

Now those of you who have watched the latest anime incarnation of Toki wo Kakeru Shoujo (The Girl who ...

Summer Wars is a perfect example of a story biting off more than it can chew.

The film opens with an introduction to ‘OZ’. An information network that controls and monitors electronic services all over the world: from shopping to competitive gaming to healthcare facilities. Think the current internet age, but even more extreme.

Then we’re introduced to Kenji, a math wiz who works as a moderator for Oz and has a crush on a girl named Natsuki. A few moments later we’re introduced to this crush of his who begs him to come with her to visit her family’s summer home. Thus kicking off the ...

I've waited eagerly for this movie and what a disaster it turned to be.

Now, don't get me wrong: it's not horrible in its wholeness. Actually, it's quite good at the beginning: lovable characters with a Miyazaki-like style of interaction between them, overall realistic setting, great art and animation. But everything ends up in ruins once the plot enters the scene. It’s simply illogical in relation to its own world that is just like our own.

So if you can cope with a lame plot, you can even enjoy the movies because, like I said earlier, it’s quite good in its other aspects. But for ...
