* AlternativeCharacterInterpretation: Everyone (except Jack). Some people include their backstories from the book in the movie, while others prefer to keep them divided. Even the writer and some artists working in Dreamworks have their own way of viewing the series.
** Pitch. Was he only manipulating the other characters (mostly Jack), and wanted to create a world filled with fear for his own selfish pleasure? Or was he a very lonely man who only wanted to be believed in, and truly wanted Jack as his friend? The scene in Antarctica shows a more complex side of him, making it hard to tell which interpretation is right. Of course, you could TakeAThirdOption and say they're ''both'' right.
** According to the DVD's audio commentary and the movie's script, Pitch was definitely genuine in his opening up to Jack, and truly hated being alone. Pitch probably empathizes with Jack, and may really view him as a potential friend.
** Bunnymund. Some people think he's the same as in the book, while others tend to keep them divided. The fact the two versions are vastly different doesn't help.
** Tooth and Jack's relationship. Some people see her as a mother figure for Jack. Others are okay with her being a possible love interest.
* AngstWhatAngst: When Jack [[spoiler:discovers his memories of his previous life, he chooses to focus on the fact that he saved his younger sister, instead of the fact that he died in the process.]]
* AwardSnub: Edged out of the Oscars' Best Animated Feature nominations by the surprise choice of ''WesternAnimation/ThePiratesBandOfMisfits''.
* AwesomeMusic: Creator/AlexandreDesplat's score.
* BrokenBase: Tooth [[spoiler:punching Pitch in the face near the end]]. A justifiably angry MamaBear, or a step too far?
* CriticalDissonance[=/=]AcclaimedFlop: The film received mostly positive reviews from critics, but cost $145 million to produce and only made $103.2 million at the North American box office, becoming {{Dreamworks Animation}}'s lowest grossing film domestically since ''WesternAnimation/FlushedAway''. According to Wikipedia, the total worldwide take was $303 million, but Dreamworks saw little of that money once budget costs and the distribution fee owed to ParamountPictures were tallied up -- they ultimately lost $83 million on it.
* CrossoverShip: Jack/Rapunzel is a popular couple in ''SugarWiki/RiseOfTheBraveTangledDragons'', as is Jack/Merida and Jack/Hiccup. Also, now that Disney/{{Frozen}}, an adaptation of ''Literature/TheSnowQueen'', has been released, Jack/Elsa has become immensely popular. There's also a small following for "Frosting" ([[PeterPan Wendy Darling]]/Jack Frost), as Jack's personality is similar to Peter's.
* DieForOurShip: Some people love the Frostbite/Rainbow Snowcone (Jack x Toothiana) pairing. Others see Tooth as a mother figure for Jack. Some people support crossover pairings, like Jack/Elsa or Jack/Rapunzel. Others prefer Jack/Pitch or Jack/Bunny.
* DracoInLeatherPants: Pitch has as many fangirls as Jack. Some have even said, without a single trace of sarcasm, that he's just a complete [[TheWoobie woobie]] who should be forgiven for all his misdeeds (which, y'know, includes his attempts to rule all the children with fear). More fangirls have gone on to compare him to Ralph from Disney/WreckItRalph in that they're villains who want to be accepted, even though they have almost ''nothing'' in common and that unlike Pitch, the most villainous thing Ralph ever did was smash a cake.
* EnsembleDarkHorse: Cupcake and Baby Tooth.
** Phil the Yeti, to an extent.
** Despite only a few seconds of screentime, the little mouse is beloved in Latin-America. The Latin-American dub has the Tooth Fairy say that the mouse is from the "Latina division", because in Latin-America, it's a little mouse named Perez who leaves children money when they lose a tooth.
** The fans are also very fond of Jack's sister (who isn't named and only appears once) and Pitch's daughter (who doesn't even appear in the movie).
* EstrogenBrigade: ''Jack Frost''. Lampshaded rather nicely in a [[http://rufftoon.tumblr.com/post/26685571155/wow-the-influx-of-jack-frost-fanart-is-almost comic]] drawn by one of the film's story artists.
* FanNickname: Heavy Weapons Santa for North, especially among the [[VideoGame/TeamFortress2 Team Fortress 2]] fandom, due to his resemblance in size, mannerism, and nationality to a certain, well, Heavy Weapons Guy.
* {{Fanon}}: Jack's sister is never given a name, but the most popular name in the fandom is Emma.
* FanPreferredCouple: The three most popular ships are Jack/Tooth, Jack/Bunny and Jack/Pitch. Jack/Jamie, Bunny/Tooth and Pitch/Sandy aren't as popular but still have a following.
* FoeYayShipping: Any of the times Pitch is paired with a Guardian, particularly [[Main/NotSoDifferent Black Ice]] (Jack/Pitch), [[Main/OppositesAttract Black Sand]] (Pitch/Sandy), and Cavity (Tooth/Pitch).
* GeniusBonus: The magic sleigh, heavy furs, reindeer and going up and down chimneys are all straight from Siberia, where Saint Nicholas was interpreted as a kind of super-shaman, who flew out the smoke-hole of his medicine tent and travelled the spirit world in a sleigh pulled by reindeer. Now consider that Santa's accent isn't just Russian, but eastern Russian.
* HilariousInHindsight: Wait, Santa is going up against someone named [[Film/SantaClaus1959 Pitch?]]
** A character [[WesternAnimation/TheNightmareBeforeChristmas named Jack is going up against the Boogieman]], you say?
* IdiosyncraticShipNaming: Ship names include Sweet Tooth for Bunny/Tooth, Rainbow Snow Cone or Frostbite for Jack/Tooth, and Snow Bunny or Jack Rabbit for Jack/Bunny and Black Ice for Jack/Pitch.
** Black Sand for Sandman/Pitch.
** Braces: Sandman and Tooth.
** Dust Bunny for Sandman/Bunnymund.
** Black Belief for Pitch/Jamie.
** Dark Chocolate or Rotten Eggs for Pitch/Bunnymund.
** Black Christmas and White Christmas for Pitch/North and Jack/North, respectively.
** Eggnog for Bunnymund/North.
** Cavity for Pitch/Tooth
** The Black Ice ship has now been expanded to include Golden Frost for Kozmotis/Jack.
* JustHereForGodzilla: Quite a lot of people went to see the movie just because of [[PrettyBoy Jack Frost]].
** Alternately, those who wanted to see it not because of the plot or characters, but because of the incredible animation.
* LauncherOfAThousandShips: Jack Frost. He's paired with the other Guardians, Pitch, and Jamie. There's also a new crossover ship with him in it made every minute, the most popular being with [[{{Disney/Tangled}} Rapunzel]], [[{{WesternAnimation/Brave}} Merida]], and [[WesternAnimation/HowToTrainYourDragon Hiccup]]. And there's already quite the amount of [=OCs=] being shipped with him as well. [[http://jack-frost-group.deviantart.com/gallery/36261346#/d5n5ygb And the original, people!]]
** [[AnIcePerson Very]] [[BirdsOfAFeather predictably]], the Jack/[[Disney/{{Frozen}} Elsa]] crossover ship has quickly grown to rival the popularity of the other three, and some fans pair him with Elsa's sister Anna instead. There's also a small but vocal minority who speculate that Elsa and Anna are [[EpilepticTrees somehow]] [[AbsurdlyYouthfulParents Jack and Rapunzel's]] ''daughters''.
* LuckyTranslation: The Italian equivalent of "sweet dreams" is "sogni d'oro", which literally means "golden dreams".
* MemeticMutation:
** A lot of the fanart is made to draw the Guardians as humans. Tooth is undoubtedly the most popular for this, with Bunnymund following.
** Early on in the fandom, someone pointed out that without audio for Jack's "and the Easter Kangaroo" line, it looked like he was saying "You're an asshole". Double points for him pointing towards the camera. Needless to say, it caught wind with the other fans.
* {{Moe}}: [[spoiler:Little Easter Bunny.]]
** Sophie.
* MoralEventHorizon: [[WoobieDestroyerOfWorlds Pitch]] killing [[spoiler:[[DisneyDeath Sandman]]]]. That's when we know he's willing to do anything to be believed in no matter how horrible.
** If he didn't cross it then, he certainly did in the climax when [[spoiler: he was ready to either kill Jamie or [[MindRape turn him into a fearling]]]]. That was the first time he made it clear he WouldHurtAChild.
* ShipToShipCombat: A rather odd crossover example, but fans who ship Jack with [[Disney/{{Tangled}} Rapunzel]] sometimes get into dispute against those who prefer to ship him with [[Disney/{{Frozen}} Elsa]], while the latter group of shipper are also frequently at war with fans of [[FoeYay Hans/Elsa]].
* UglyCute: The elves.
* VisualEffectsOfAwesome: Everything is detailed to the last hair.
* TheWoobie: Jack Frost. [[spoiler:He never sees his little sister again after saving her, then spends 300 years all alone with nobody knowing he exists.]]
** Bunny becomes this after [[spoiler:Pitch's nightmares destroy his eggs and then cause the children to lose their belief in him.]]
** Pitch too, once you know he came through the same hell as Jack but wasn't as lucky as he was. Then when you add in his backstory from the books...
** Tooth. In the film, children stop believing in her, making her palace disintegrate and her wings to stop working. But if you know ''her'' backstory...
