!!Film
* BileFascination: Those who joined the ''Avatar'' fandom after the release of the movie can't help but be curious to know why it was panned to kingdom come.
* BrokenBase:
** The debate over the movie casting was so intense that entire forums were divided over it, with those supporting the casting and those against it being banned for their opinions. Protesters considered those who supported the casting as blind and shrugging off a big issue, while those that eagerly anticipated the movie thought the protesters were [[NoTrueScotsman not 'true' fans.]]
** Firebending only being able to manipulate preexisting flames ([[spoiler:except in special circumstances]]). People tend either to be upset that [[TheyChangedItNowItSucks it's not the same as in the show]], or feel that it now fits with the other three bending types in that it doesn't create the bendable element.
* EnsembleDarkhorse:
** Francis Guinan as Pakku has been noted by several reviewers to be the one actor to escape the film with his dignity intact, putting real effort and emotion into his scant screen time in stark contrast to everyone else.
** Seychelle Gabriel's performance as Yue also was moderately well received by fans, and Bryan and Mike would later cast her in ''WesternAnimation/TheLegendOfKorra''.
** Even though his portrayal may not have been entirely accurate to the character he was playing, most critics noted that Shaun Toub as Iroh was one of the few cast members who put effort into their performance.
* FandomBerserkButton: For those fans of the source material who acknowledge it at all. Many ''Avatar'' fans refuse to admit that this movie even ''exists''.
* FightSceneFailure: Viewers have criticized all of the fight scenes.
** Probably the ultimate example is the [[FanNickname Pebble]] [[MemeticMutation Dance]]: As the [[http://www.youtube.com/watch?v=_RpgbZcHk_A Earthbender prisoners stage their revolt]], six Earthbenders move in precise choreography, stomping the earth and releasing a [[ScreamingWarrior mighty battle cry]] … and a tiny rock barely bigger than a football floats by very, ''very'' slowly. A ''seventh'' Earthbender then launches it at a guard. A fan theory suggested that the dancing Earthbenders were actually responsible for making the earth walls previously used to block the fire blasts, but the scene alludes to the cartoon, in which Haru's father ''was'' the one who made the earth wall. It [[MugglesDoItBetter probably would have been more effective]] if all seven benders instead each picked up a moderately sized rock and [[MundaneSolution just threw them]].
** The above fight scene was one of a few that were shot with a single camera, [[TheOner with no jump cuts]]. This leads to the problem of showing the audience a large number of [[MookChivalry mooks standing in the background, not doing anything while their friends are getting knocked senseless.]]
* FoeYay:
** The ending of the Oasis fight was significantly more… Zutara-ish.
** Not to mention some of Zuko's interactions with Aang.
* HamAndCheese: Aasif Mandvi plays Zhao pretty similarly to how he plays himself on ''Series/TheDailyShow'', only, well, evil.
* HilariousInHindsight:
** "The Ember Island Players" episode, which came out during the production of the movie. Needless to say, many jokes were to be had using footage from that episode to show how bad the film was -- particularly its last line, wherein the heroes say the show they just saw was awful but the effects were nice.
** Seychelle Gabriel (Movie Yue) voicing Asami in ''WesternAnimation/TheLegendOfKorra'', a character first intended as a simple RomanticFalseLead but was changed to become much more prominent when she became popular with the fans. [[spoiler:The hilarity doesn't reach its peak until the ''end'' of the show, though, where Asami ended up becoming the titular Korra's final ''love interest''.]]
* InternetBackdraft: Online criticism of the film reached apoplectic levels. Luckily, capital letters and boldface are unlimited resources.
%%* JerkassWoobie: Zuko, when he's not [[LargeHam yelling or being his general angry self.]]
* MemeticMutation: Many, mostly related to [[Narm/TheLastAirbender the unintentionally hilarious moments.]]
** Before the movie had even come out, early test screening reviews mentioned a scene that has turned the phrase "punching the fish" [[http://fc05.deviantart.net/fs71/f/2010/063/7/3/PUNCH_A_FISH_IN_THE_FACE_by_Booter_Freak.png into a meme]].[[note]]He actually stabs it with a knife.[[/note]]
** '''"BRING ME … ALL YOUR ELDERLY!"''' (Zuko's line when he's searching for the Avatar in the Southern Water Tribe makes it sound like he has a fetish for elderly people. He explains himself better in the show.)
** The pebble dance, the most notorious example of FightSceneFailure mentioned above.[[note]]Six Earthbenders. Four seconds of ''kata''. One rock, slightly larger than a human head, gently floating along.[[/note]]
** Kat-tackle (Katara pushing over a random guard and then just standing there).
** Zhao constantly mentioning the secret library (Movie!Zhao mentions the library several times, as opposed to Animated!Zhao, who vaguely mentions it once).
** Ozai's glowing ass (from a screenshot in which the source of light appears to be Ozai's rear end).
** Yue's line about believing in beliefs, and her penis hair (how it looks like when viewed from the [[http://i747.photobucket.com/albums/xx111/aangthony/wtf-tla/101.jpg back]].)
** [[http://www.youtube.com/watch?v=e5J7inpYSoE AANG! JUST ONCE!]] (Fans of the show got annoyed at how 'Aang' was pronounced 'Ahng.')
** X, there is Y under your feet! Why don't you fight? (Aang motivates the imprisoned Earthbenders by pointing out that the material that they can ''[[DishingOutDirt magically manipulate]]'' was ''[[ForgotAboutHisPowers completely surrounding them]]''.)
%%** [[AC:X scene was cut from the movie because it was too "distracting".]]
%%** [[FelonyMisdemeanor It really hurt!]]
%%** The Fire Nation and Their Machines.
* MisBlamed: Some sources have redirected responsibility for many of the film's flaws from Shyamalan to ExecutiveMeddling.
* {{Narm}}: [[Narm/TheLastAirbender Has its own page.]]
* NeverLiveItDown:
** Played straight with Creator/MNightShyamalan, who has yet to distance himself from the spectacular failure of this film on top of his [[Film/TheVillage previous]] [[Film/LadyInTheWater three]] [[Film/TheHappening outings]]. Likewise, Creator/{{Nickelodeon}} and Creator/{{Paramount}} have not been allowed to forget that they paid for it.
** The way Yue's hair is styled in the back. People have infamously nicknamed it the "penis hairdo".
** The [[https://www.youtube.com/watch?v=_RpgbZcHk_A Earthbending sequence]] has been the victim of many EpicFail and FightSceneFailure jokes[[note]]For comparison's sake: in the show, a single Earthbender can take out a Tank; six Earthbenders would be enough to level a small city[[/note]].
** The mispronunciation of the characters' names; for example, Aang being pronounced as "Ong", and Sokka is pronounced "Soh-ka". The fandom went to town with this and it quickly became symbolic of the film's faults.
* TheScrappy: Katara's live-action incarnation has far fewer fans than her cartoon counterpart, mainly for hardly being like Katara is in the cartoon and her actress having a severe case of DullSurprise. It also doesn't help that the script removed many of her strong CharacterDevelopment moments and gave most of the rest to Aang.
* SignatureScene: The Earthbender [[LockingMacgyverInTheStoreCupboard prison]], because it's a perfect showcase of the film's … [[PlotHole problematic]] {{adaptation|alWimp}} of the show. The Pebble Dance in particular has gone {{memetic|Mutation}}.
* SnarkBait: Oh, so very much. It's in reviews, it's in forums, and it's in ''Wiki/TVTropes'', all because the movie is so awful.
* SoBadItsGood: For all the snark the movie earns, it's good for riffing on at least.
* SpecialEffectFailure:
** The CGI animals.
** At the beginning, Katara splashes an off-screen Sokka with water, but he is completely dry when he appears.
** In what is purportedly an arctic area, you can't see anyone's breath.
** At times, the Waterbending is not even animated.
** The Firebending is pretty much nothing but poorly composed live-action fire elements with CG that even the film version of ''Film/{{Spawn}}'' would reject.
** The last-minute 3D conversion was universally panned and earned a one-off UsefulNotes/GoldenRaspberryAward; Creator/RogerEbert called it the nail in "low-rent 3D".
* StrangledByTheRedString: Yue and Sokka's romance gets this treatment. In the show, their romance is developed and they get several scenes together. In this movie, it's reduced to exposition.
* TheyChangedItNowItSucks: Long before the movie was anything more than a casting list and a few trailers, fans were complaining about changes to the source material. One of the biggest examples from the movie once it finally came out was the pronunciation changes, which Shyamalan deliberately included to make the character names sound closer to their "correct" Asian pronunciations (even though most of the names were made up) than the Americanized pronunciations from the cartoon. Fans were not pleased.
* TookTheBadFilmSeriously:
** Shaun Toub and Dev Patel as Uncle Iroh and Prince Zuko respectively, though at least the latter was somewhat close to his character's original portrayal.
** Aasif Mandvi as Commander Zhao also puts in one of the movie's better performances.
* UncannyValley: Appa's face, in both the movie and the [[TheMerch tie-in toys]]. Samples [[http://screenrant.com/the-last-airbender-toys-kofi-44634/ here]].
* UnfortunateCharacterDesign: [[http://ic.pics.livejournal.com/aerieel/26055487/4497/4497_original.jpg Yue's hair style didn't fare well in the transition from cartoon to live action]], as from the back many claim it resembles a penis.
* UnfortunateImplications:
** [[http://io9.com/5111680/avatar-casting-makes-fans-see-white Many fans of the show]] saw the decision to cast white performers in the leads as a RaceLift to exclude Asian actors from the roles. The casting call as for "Caucasian or any other ethnicity" suggested a preference for white actors, and it also [[InterchangeableAsianCultures suggested that people of Korean descent wear a kimono]].
** ''Website/TheAgonyBooth'' [[http://www.agonybooth.com/movies/The_Last_Airbender_2010.aspx calls out]] an apparent sexist tone in the film, pointing out that a number of important moments female characters had in the animated series (Katara's speech to the imprisoned Earthbenders, Yue realizing she can [[spoiler:sacrifice herself to restore Waterbending]]) are given to male characters instead.
* WTHCastingAgency: The casting of all the main characters has been met with this reaction with certain examples standing out:
** Aasif Mandvi as Zhao. Mandvi is a primarily comedic actor best known for his work on ''Series/TheDailyShow''. Shockingly enough though, he ended up being one of the most faithful characters to the source material.
** Nicola Peltz and Jackson Rathbone as Katara and Sokka, given the white actors looked nothing like the characters in the cartoon. This was made worse not just by the fact all the Waterbender extras ''were'' Asian or Inuit actors, meaning the main characters don't seem to belong to their own tribe, but also by their DullSurprise acting.
* WTHCostumingDepartment: Iroh having dreadlocks.

!!Video Game
* BreatherLevel: "Surrounded" is so easy that it's almost funny. All you do is stand in the middle of the room and shoot at Fire Nation soldiers. You can get the level's collectables when you're not busy shooting fireballs, but that's it for that level.
* ThatOneBoss: The final BossBattle with Zhao can be difficult at certain points. For example, closer to the final stage, he summons more soldiers to fight and he also gets down to fire at you. You'll get hit by Zhao's fire-blasting as well as the sword attacks.
