History YMMV / HarryPotterAndThePrisonerOfAzkaban

** [[Series/RuPaulsDragRace Tia Kofi]] was a Hufflepuff before finding her true calling in drag.

* AuthorsSavingThrow: The AdaptationExpansion for the Time Turner sequence is widely agreed to be a big improvement over how it was handled in the books. The film adds a lot more {{foreshadowing}} for the twist (like having Hermione regularly [[StealthHiBye pop up unexpectedly]] in class) so that it doesn't come out of nowhere, and the PlotTwist [[spoiler: that Harry himself conjures the big Patronus]] is properly set up by showing Future!Harry and Future!Hermione influence other past events too--like throwing pumpkin seeds to warn that Fudge is coming. The film also makes it more clear Time Turners can't actually change the past, but can only establish a StableTimeLoop (which requires ''flawless'' pre-planning to pull off successfully), settling the question of why the characters don't just use Time Turners to undo things like [[spoiler:Cedric Diggory's death]] and [[spoiler:Voldemort's resurrection]].

** Sir Cadogan, the portrait that takes over guarding Gryffindor Tower for The Fat Lady after she's attacked by Sirius Black, and whose work style involves setting "ridiculously complicated" passwords, and changing them at least twice a day. Is he stark raving mad, or ProperlyParanoid taken UpToEleven? The fact that he had no problem with a student writing them all down on a piece of paper that anyone could read seems to imply the latter, however.

* AnnoyingVideoGameHelper: Ron and Hermoine in the console versions. While you're wandering around in the open world parts of the game, whichever one you aren't playing as at the moment will ''constantly'' remind you where you need to be, what you need to be doing, or just drop endless CaptainObvious hints.

* HeartwarmingInHindsight: Madam Pomfrey checks over Harry when [=McGonagall=] asks, following the Dementors searching the train; she nods in approval when Harry reveals that Lupin gave everyone chocolate. Lupin later reveals that Madam Pomfrey personally escorted him to the Whomping Willow before every full moon. Looks like he learned wizard medical care from the best.

* ShippingGoggles: The series has enough of this to fill a page, but this entry probably has the best example, what has been dubbed "The Symbolic Flight." This theory states that because Harry and Hermione flew together on Buckbeak without Ron, that they are destined to be together -- ignoring the fact that Ron was only not present because he broke his leg earlier, or that it's most likely there to make up for Hermione missing out on so much in ''Chamber of Secrets'', where Harry and Ron flew a car, and then had adventures while [[spoiler:Hermione, like Ron in this book, was passed out and missing in the climax]].

** Snape's behavior in this novel, where he's at his most emotional and unhinged has drawn a lot of views. Notably fans invoke information from later series to explain why he was so personally angry at Lupin. Others however note that his taunting at Harry by using [[spoiler:Lily's own insults about James to the latter, and then having the latter remind him, much as Lily did in ''The Prince's Tale'' that James did save his life, and repeating the same conversation, while in the finale shouting at Harry that James deserved to die because he was too arrogant to distrust Sirius is more or less him vicariously trying to argue that Lily was a fool for choosing James]] and wondering WhatDoesSheSeeInHim.
*** In terms of his behavior towards [[spoiler:Black]] in the Shrieking Shack, [[spoiler:did he want revenge because he believed Black was the one who sold out Lily to Voldemort? Or was he one of the Death Eaters who knew Pettigrew was the actual spy, but still blamed Black for her death because he decided not to be the Secret Keeper himself.]]

** Hagrid calls out Ron for valuing his pet over his friendship with Hermione when it seems that Crookshanks has eaten Scabbers. [[spoiler:The narrative reveals that Crookshanks knew that Scabbers wasn't a real rat but didn't tell anyone besides Sirius, despite the fact that the Gryffindor Head of House is also an Animagus; Pettigrew took the opportunity to fake his death]]. Here is the thing: Crookshanks's first encounter with Ron was ''attacking him'' and going for Scabbers. From the pet witch's reaction -- "NO CROOKSHANKS NO!" it's reasonable for Ron to believe that Crookshanks is a bit trigger-happy and he ends up being right that the cat was aiming for his pet. The other thing is that Hermione for most of the book refuses to do anything about Crookshanks attacking Scabbers, defending his violent behavior as acting like a cat because of CatsAreMean by nature. While one could attribute it to Hermione being overworked and not thinking things through, it's an insensitive thing to say. Harry acknowledges this because the evidence points to Crookshanks having eaten Scabbers. Ron even says that he'd forgive Hermione if she just apologized rather than acting like "Scabbers was on vacation," because imagine if ''your'' pet was seemingly EatenAlive with his blood left on your bedsheets. [[spoiler:Pettigrew faking his death ends up resolving the situation]]. And indeed, he does forgive her when she finally apologizes tearfully after he promises to help her with Buckbeak's case.

** To an extent, the one against Ravenclaw, but it has a little more plot-relevance, as it introduces Cup and is where Harry first manages to cast a really successful patronus.

* TheyWastedAPerfectlyGoodPlot: While Ron insists that Errol is not his owl, but just his family's in general (when Hermione, thinking about what to get for a pet, considers an owl, saying Harry and Ron both have one) it would have been nice to see him inherit Errol after losing hisnrat, rather than introducing another one (Pigwidgeon).

** Snape's behaviour in this novel, where he's at his most emotional and unhinged has drawn a lot of views. Notably fans invoke information from later series to explain why he was so personally angry at Lupin. Others however note that his taunting at Harry by using [[spoiler:Lily's own insults about James to the latter, and then having the latter remind him, much as Lily did in ''The Prince's Tale'' that James did save his life, and repeating the same conversation, while in the finale shouting at Harry that James deserved to die because he was too arrogant to distrust Sirius is more or less him vicariously trying to argue that Lily was a fool for choosing James]] and wondering WhatDoesSheSeeInHim.

* CrossesTheLineTwice: Oliver Wood finds out that Harry received a Firebolt anonymously, and it was confiscated by the teachers. He says he'll talk to Professor [=McGonagall=] and convince her to give back the broom. A few weeks later, he goes to Harry and sheepishly said that their Head of House refused. Apparently Wood said that he didn't care if the broom threw off Harry as long as he caught the Snitch, and Professor [=McGonagall=] got "shirty" with him.

* AwesomeMusic: The GBA game's soundtrack is gorgeous through and through, but the standout is the [[https://www.youtube.com/watch?v=wjMUZZ-m5OQ final boss battle theme]], feeling suitably intense and ominous, and it really pushes the GBA's soundcard to its limit.

* ThatOneBoss: [[OurWerewolvesAreDifferent Lupin]] in the GBA game. It's a very odd fight as Harry and Hermione's spells do almost nothing to him, meaning you have to rely on [[GuestStarPartyMember Buckbeak]] for damage output. Problem is, Lupin is still stronger than him, and it's an automatic defeat if his health drops to zero. [[GuideDangIt The game offers no straightforward solutions to this]], but the best one is to buy a particular wizard card from Fred and George's shop that can heal party members.

* ContinuityLockOut: This was the point when the movies started to get hard to understand for anyone who wasn't already familiar with the books. Most notably, this movie never makes it clear who Padfoot, Wormtail, Moony, and Prongs are, despite later movies operating on the assumption that the viewers all know.

* AuthorsSavingThrow: The AdaptationExpansion for the Time Turner sequence is widely agreed to be a big improvement over how it was handled in the books. A few readers missed the {{Foreshadowing}}, and thus found the twist to come really out of nowhere. The film expands on this by having Hermione suddenly turning up out of nowhere in classes at points throughout the film. Also the twist [[spoiler: that Harry himself conjures the big Patronus]] is foreshadowed by having more events influenced by the time travellers - throwing the pumpkin seeds to warn that Fudge is on the way, for example.

* PresumedFlop: It enjoys the title of being the lowest grossing film in the series - as it was the only one not to gross $1 billion worldwide. Its actual gross was still $800 million!

* FunnyAneurysmMoment: Or perhaps HilariousInHindsight, depending on how you feel about Peeves. This is the last ''Potter'' video game to feature Peeves before he [[ChuckCunninghamSyndrome disappears from the game series]]. In the PC version, he's the FinalBoss, and the following exchange occurs after he's been driven off for good:

* {{Padding}}: The quidditch match against Slytherin, which is essentially just what was supposed to be the GrandFinale of the quidditch scenes at Hogwarts, and where the team finally wins the cup.

* WhatAnIdiot: Sirius and Hermione after Lupin's transformation.
** Sirius, who knew of Lupin's condition, tries to calm down Lupin not by immediately transforming into a dog, but by trying to remind him of his humanity. You would think if he knew Lupin as a boy and knew about the transformation he would know those kind of appeals don't work. (Not even taking into account the Marauders backstory that the film never mentions.) Remedied when he transforms soon after to draw Lupin away from the kids.
** Hermione, who was the one who guessed Lupin was a werewolf after Snape's homework assignment, tries to approach Lupin once he's transformed. Again, if she'd done her homework, she should know that wouldn't work.

* FunnyAneurysmMoment:
** At one point in ''Literature/HarryPotterAndThePhilosophersStone'', Scabbers bit Goyle on the knuckle (which was even referenced by Fred and George Weasley in ''Prisoner of Azkaban''). Here, it's revealed that [[spoiler:Scabbers was actually Peter Pettigrew, who was the true person responsible for leaking Lily and James Potter's location to Lord Voldemort and thus their deaths]]. Coupled with the later revelation in ''Goblet of Fire'' that Goyle's father was most likely one of [[spoiler:Pettigrew's]] comrades among the Death Eaters, it becomes somewhat disturbing.
** Ron carrying him around in his pocket and Scabbers even falling asleep on Harry's bed at one point in ''Philosopher's Stone''. Counts in-universe too as when [[spoiler:Pettigrew tries to plead with Ron for mercy, Ron (with appropriate anger and disgust) points out he let the rat sleep on his bed]].
