History Anime / SummerWars

** Love Machine begins by crowd sourcing an encryption to break a password to gain high level admin privledge making it effectively the legitimate owner of Oz. Stealing accounts which are evidently able to command computer resources allows Love Machine to act as bot-net. Additionally most of Love Machine's mischief comes from abusing other legitimate access from accounts it has stolen. All of this is very much real to life in concept.

* HollywoodHacking: Most of the movie.

* WhatDoYouMeanItsNotAwesome: The [[spoiler:koi koi match for the fate of the world]] starts out pretty awesome already, but then [[spoiler:John and Yoko grant Natsuki an angelic avatar]] and it gets crazier from there, culminating in a meteor strike-esque (with an explosion of CherryBlossoms upon impact) [[spoiler:slamming down of the last card]].
** Also, scribbling on notepaper and rapidly tapping keyboards have never been so epic.
** Epic use of a rotary dial phone and an address book!

* FridgeBrilliance: At first, it seems to be a remarkable coincidence that [[spoiler: the rogue AI that steals Kenji's avatar in its initial attack on Oz was written by the black sheep of the family he's staying with]]. Of course, since Kenji became involved in the entire mess by responding to an e-mail via cell-phone, [[spoiler: Love Machine almost certainly knew Kenji's physical location, was likely able to correlate it with the location of Wabisuke's home, and probably picked that particular avatar just to screw with its creator.]]

* HilariousInHindsight: The climax of the movie prominently features [[spoiler:a Japanese asteroid sample-return probe being hijacked by Love Machine and set on a re-entry profile that will destroy a nuclear power plant]]. The Japan Aerospace Exploration Agency's [[http://en.wikipedia.org/wiki/Hayabusa Hayabusa mission]] was a similar asteroid sample return probe which did return to Earth in the summer of 2010, and which did experience failures leading to a barely-controlled crash-landing in Australia.

* ViewerGenderConfusion: Kazuma looks a lot like a girl and sounds like a girl, but he's a boy.

* CuteShotaroBoy: Kazuma has his moments.

* EverythingsBetterWithBunnies: Kazuma's avatar.

** BadassFurry: King Kazma, hands down.

* TookALevelInBadass: ''Many'', Kenji in particular.

* BadassAdorable: Well, Kazuma is the one controlling King Kazma, so...
* BadassFamily: The Jinnouchi family is extremely close knit, warm, and hospitable... and will [[TheDeterminator stop at nothing]] to keep a rogue AI from taking over TheMetaverse and [[spoiler: dropping a satellite on a Nuclear reactor.]]
* BadassFurry: King Kazma, hands down.

* BadassGrandpa: Mansuke (Kazuma's grandfather, filling this requirement) taught Kazuma (and thus King Kazma) everything he knows about martial arts, attacked Love Machine (by this time an extremely strong martial arts master)by himself to buy Kazma time to recover, and he has a NINJA SQUID for an avatar.

* EigenPlot: In a story that revolves around the theme of family, there's no surprise that the 'war' the titles refers to is waged by pooling all the various family member's resources and skills each member has. Who would have thought being good at card games, math problems, and fighting games would be so critical for survival?

Has a manga spin-off: ''[[http://www.mangafox.com/manga/summer_wars_king_kazuma_vs_queen_ozu/ Summer Wars: King Kazuma vs Queen Ozu]]'', a prequel which focuses on Kazuma.

* NiceJobBreakingItHero: Kenji initially thinks it's his fault that Love Machine was released because he cracked the code. [[spoiler:It's ultimately subverted: not only did several people around the world solve it before him, but he had made a mistake on the last word anyway.]]

Has a manga spin-off: ''[[http://www.mangafox.com/manga/summer_wars_king_kazuma_vs_queen_ozu/ Summer Wars: King Kazuma vs Queen Ozu]]'' which focuses on Kazuma.

* YourPrincessIsInAnotherCastle: Love Machine's plan to smash a satellite into a nuclear power plant is thwarted...then it aims the satellite [[spoiler:at ''the house'' instead]].

* SeriousBusiness: Hanafuda, koi-koi version.

** King Kazma is a likely reference to ''CaveStory''. King and Kazuma are two characters from the game. The anthromorphic rabbit design supports this.

* WhatCouldHaveBeen: Recent news revealed that ''Summer Wars'' was rejected by WarnerBrothers... in which case, an entirely new dub would've had to be made! Who knows how much the chances of an Oscar nomination would've changed if that had happened!

* MissionControl / VoiceWithAnInternetConnection: Sakuma. He co-ordinates the Jinnouich counterattack on Love Machine from his dorm room.

* [[{{Ptitle7wmurkq3abiw}} Design Student's Orgasm]]: OZ all the way.
