History YMMV / SuperNatural

*** A smaller moment occurs in the season one finale. [[spoiler: When Azazel possesses John and holds both Sam and Dean against the wall, he proceeds to [[KickTheDog gleefully taunt them about their mother's death]] at his hands. In response, Dean turns the tables and [[DidYouJustFlipOffCthulhu taunts Azazel over his own kids' deaths]] at his hands, leaving the ever-so-smug and sadistic Azazel [[OOCIsSeriousBusiness at a loss for words]]. Although the moment is undercut in that Dean is [[DoNoTauntCthulhu nearly tortured to death]] right after, it's still satisfying to see someone finally get to Azazel.]]
** [[spoiler: While it may have been [[ILetYouWin part of Lilith's plan all along]], Sam using his demon powers to kill Lilith in the season four finale is still rather satisfying, given that she's a vile PsychopathicWomanchild who possesses little girls and torments their families, EatsBabies, and previously subjected Dean to a CruelAndUnusualDeath.]]

** Crowley. It turned out that [[spoiler:his mother, Rowena, sired him at a solstice winter orgy, so he didn't know his father, she later abandoned at the age of 8, tried to sell him for two pigs (when he was worth at least three)...]]

** In "My Heart Will Go On", Balthazar bragging how, thanks to his meddling with the timeline, Creator/CelineDion is now a "destitute lounge singer somewhere in Quebec" can sound extra mean-spirited since Dion was diagnosed with a rare and crippling neurological disorder in 2022. Presumably in the new timeline, she would have to deal with that in addition to being destitute.

** Back in the show's heyday, John Winchester was mainly seen as a [[JerkWithAHeartOfGold highly flawed yet ultimately benevolent]] parent who did what he thought was [[ForYourOwnGood necessary to keep his sons safe]], even if it strained his relationship with them. However, come TheNew10s, with the public becoming more aware of how deep the effects of [[ParentalNeglect child neglect]] are, many have turned around on their original perception of John and deemed him an absolutely [[AbusiveParents horrible parent]] who ruined his sons' lives due to his obsession with [[CrusadingWidower avenging his dead wife]]. As a result, John is now the [[BaseBreakingCharacter most controversial character]] in the ''entire series'', with fans split over whether or not he's a good portrayal of ParentsAsPeople or the worst father in the world.
** Jo [[DieForOurShip received tons of hate]] when the show was in its prime, particularly [[IncestYayShipping among fans who shipped Dean with Sam]], with many finding her dull and uninteresting DamselInDistress and a poor LoveInterest for Dean. As a result, she was written out of the show shortly after the second season. However, her return in season 5 in which she received [[spoiler: [[TearJerker an incredibly emotional death scene]] and [[DefiantToTheEnd epic final stand]]]] won [[RescuedFromTheScrappyHeap some people over]]. This only increased with time, as fans new to the series repeatedly stated their confusion as to why Jo received so much hate early on, causing old fans of to look back at her character and actually agree that she wasn't as bad as they made her out to be. Nowadays, a lot of her previous hate has been chalked up to "Wincest" shippers who just weren't happy that their ship wouldn't happen.

* OvershadowedByControversy: Season 15, while the final season of the series, tends to be more well-known for the infamous scene where [[spoiler: [[LoveConfession Castiel declares his love for Dean]], effectively rendering [[FanPreferredCouple Destiel]] canon, only for him be killed in a [[{{Narm}} hilariously anticlimactic fashion]] almost immediately after]], making for one of the fastest BuryYourGays moments ''ever'' and pissing off both shippers and non shippers alike. Even those who didn't watch the show [[ItWasHisSled became aware of it]] due to how much it trended on social media, up to the point where it's widely considered an example of how PanderingToTheBase can go horribly wrong.

** Bela was seen as TheScrappy during her first few appearances in the show, with many despising her for [[ChronicBackstabbingDisorder constantly screwing Sam and Dean over]], not receiving any real comeuppance for her actions, and generally just being more of a nuisance than an actual threat. However, her final appearance in which [[KarmicDeath karma comes back to bite her]] actually made many [[AlasPoorScrappy feel sorry for her]] when it's revealed that [[spoiler: she made a deal with a demon to stop her parents from [[FreudianExcuse sexually abusing her as a child]], with her ultimate fate being torn apart by hellhounds and dragged off to Hell for all eternity.]] As a result, some looked back at her previous appearances in a [[CerebusRetcon different light]] and began to view her more favorably, with a few even thinking that she could have been a fun and interesting villain if she was just written better. While she still has more detractors than fans, she's at least evolved to BaseBreakingCharacter status, in contrast to the near-universal hate she received early on.

** Bonnie/[[spoiler: Vesta]] from "Rock and a Hard Place" went on to play [[Creator/LindyBooth Cassandra Cillian]] in the cult series ''Series/TheLibrarians2014" one year after the episode aired.
