** Much of the fandom refuses to acknowledge the third ([[ScrewedbytheNetwork and final]]) season of the show, due to head writer Steve Marmel and the rest of the writing staff leaving the series at the end of season two. The result of this was creator Butch Hartman and slew of new writers [[StatusQuoisGod ignoring past character development]] and leaving several plot threads dangling, despite being fully aware it would be the last season. Even those who acknowledge the last season often ignore the finale episode "Phantom Planet", dismissing most of its moments as nonsensical, poorly executed, or just plain disappointing: from the group's (especially Sam's) callous reaction to [[spoiler:Danny giving up his powers]] to [[spoiler:Vlad seemingly being killed by a random asteroid]]. If a fan work does acknowledge Season 3 at all, they usually keep a few plot points, such as Danny developing [[AnIcePerson ice powers]] or the aftermath of "D-Stabilized" (the only widely-liked episode of the season), and ignore everything else. When the series eventually did see a continuation in the graphic novel ''ComicBook/DannyPhantomAGlitchInTime'', the comic ([[RunningTheAsylum which was written by a fan]]) would actually follow suit by ending with [[spoiler:most of season three's events undergoing a CosmicRetcon]].

** Many fans hate the episode "Arthur's Big Hit", because of the [[HumiliationConga treatment]] Arthur gets after he (rather understandably) gets fed up with [[AnnoyingYoungerSibling D.W.]] and punches her. One infamous example of said treatment is Binky punching ''him'' for it and his parents expressing NoSympathy over that. That said, the infamous scene of [[SignatureScene Arthur punching D.W.]] became notoriously [[MemeticMutation memed to hell and back]] in the following years.

* ''WesternAnimation/ThePenguinsOfMadagascar'': Inverted by the actual series. Most fans regard the series canonical to the movies, despite the inconsistences in the backstory of the Penguins and WordOfGod denying that to be the case.

* A majority of ''WesternAnimation/TheSmurfs1981'' fans pretend that the time-travelling saga from the ninth season never happened, and to a lesser extent, Seasons 5-8 (where the Smurflings were introduced).

* Some fans of WesternAnimation/{{Amphibia}} prefer to ignore the show's finale "The Hardest Thing" at least partially in favor of pretending show ended with at least one of the Calamity Trio staying in Amphibia instead of returning to Earth, partially out of the desire to prevent any of the girls from having to split from their respective found families (believing that it's not worth the show's intended message), but also due to what little information we're given regarding Sasha and Marcy's family lives on Earth having given fans the impression that their human parents are incompetent, if not neglectful when compared to their [[ParentalSubstitute Amphibian parental figures,]] whom those fans believe deserved to keep their respective adopted daughters. There are also some fans who disregard the show's finale in favor of ending the show with [[YouCantGoHomeAgain with the Calamity Trio being ultimately stuck in Amphibia permenantly]], believing that ending would work better with the show's message about accepting change without needing to involve The Calamity Guardian providing [[DeusExMachina Deus Ex Machinas]] that those fans believe directly contradict the show's message due to bringing Anne back from the dead and providing them with a way back to Earth when they previously gave it up to save Amphibia from The Core.

** The season eight finale "Meet the [=OddParents=]" is seen as another good ending point, as it has Timmy being able to happily interact with both his parents and his fairies, who get along perfectly. And while it ends with his parents having their minds wiped of the episode's events, they willingly consent to it, assured that Timmy is happy and safely protected by his fairies at all times. Season nine would bring in Sparky, Timmy's magical talking fairy dog who fans despised to point of him getting PutOnABus for the last season. Speaking of, the tenth and final season would then introduce a new girl named Chloe Carmichael, who Timmy had to share his fairies with; while definitely less hated than Sparky, fans still weren't amused by the creation of new major characters when much of the supporting cast who could have been fleshed out for such roles have not only been reduced to extras by this point, but some (like Trixie and Tootie) hadn't made appearances for seasons.

** Even before that, most fans of the series wish that the episode, ''Town and Out'' never happened, owing to the absolutely sadistic treatment of the Powerpuff Girls after being forced to move to a city full of horrible people.

* Loyal fans of ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' have despised ''WesternAnimation/PlanetSheen'' and wish it never happened while wondering why ''Jimmy Neutron'' wasn't just given a new season. Poor animation, lack of originality, and rampant bad acting are commonly cited reasons by fans to stay away from the spin-off. The fallout was so great that the ratings took a drastic landslide following its premiere, resulting in the series being ''[[TheFireflyEffect aired out of order]]'' and then moved from Nickelodeon to Nicktoons. Eventually Nickelodeon said "Screw it" and canceled the series without announcement, leaving the series to end on a sad note of [[AbortedArc Sheen never returning to Earth]].

** "[[Recap/FuturamaS8E9ThePrinceAndTheProduct The Prince and the Product]]" was also regarded by fans as one of the worst episodes of the series due to the main plot about Leela falling in love with the Prince of Space being boring and uninteresting, plus the segments featuring the crew as toys spliced inbetween the main plot also felt disjointed and pointless, not the mention fans felt like the "twist" that Fry was under a spell and everything was fine felt lazy and didn't sit too well. To date, it is the lowest rated episode of the series on Website/{{IMDB}} scoring a 5.3 rating.

** ''The Late Philip J. Fry'', though widely regarded as a well-written episode (it did win an Emmy Award, after all), is controversial because of the inference that, with the exception of Fry, Bender, and Prof. Farnsworth, the rest of the characters we see from then on are not the original ones we've grown to love, but duplicates from another iteration of the universe, and the original Leela lived a long and lonely life without Fry. The somewhat ambiguous nature of time travel in the show makes different interpretations possible.
** Some fans refuse to acknowledge that Calculon and Roberto were KilledOffForReal (even though Calculon has been brought back to life ''twice'', and Roberto randomly appeared in a minor role in the penultimate Comedy Central episode, then playing a fairly major role in [[Recap/FuturamaS8E3HowTheWestWas1010001 "How the West Was 1010001"]]).
** Many fans regard “Rage Against The Vaccine” as one of the worst episodes of the series due to focusing on Covid-19, which had been around for 3 years and started feeling outdated with these fans just wanting forget about the pandemic and what it brought Other issues these fans had included unfunny and painful jokes about the pandemic, characters such as Jrrr displaying out of character behavior for no reason, and for having mean spirited undertones due to showing characters constantly being angry and fighting each other.

** Some fans refuse to acknowledge that Calculon and Roberto were KilledOffForReal (even though there was an episode where Calculon is brought back to life, only to realize that no one wants him back and he ends up dying again after giving the best acting performance of his life, and Roberto randomly appeared in a minor role in the penultimate episode).

** There are several fans who don't consider anything past Season 1 canon. To a lesser extent, there are those who won't accept anything past the three-episode pilot.
** It is '''''not''''' a good idea to mention the words, "Everyone Knows It's Bendy", which introduces [[TheScrappy Bendy]], who despite spending all of his screen-time getting Bloo, Wilt, Eduardo and Coco in trouble, [[KarmaHoudini he gets off scot-free for his actions]]. Even people who aren't fans of the series hate this episode.
