History YMMV / Supernatural

** Becky Rosen was disliked by a majority of fans due to only serving as one big TakeThat towards [[LoonyFan overenthusiastic fangirls]] of the show, with most finding her annoying and grating rather than funny. However, it wasn't until the infamous [[S07E08SeasonSevenTimeForAWedding "Season Seven, Time For A Wedding"]] that fans began to genuinely loathe her, in which she forces Sam to marry her via a LovePotion, with most of it being [[DoubleStandardAbuseFemaleOnMale played for laughs]], and basically gets off [[KarmaHoudini scot-free]] at the end. Safe to say, she became one of the most hated characters in the series after that.

** [[spoiler: John literally [[EscapedFromHell escaping from Hell]] and holding Azazel down long enough for Dean to ''finally'' kill him with the Colt is ''extremely'' satisfying, given [[TheChessmaster everything the bastard pulled]] up until that point, as well as [[YouKilledMyFather finally avenging Mary's death]]. Even better is Azazel's massive OhCrap face once he realizes he's utterly screwed.]]

*** A smaller moment occurs in the season 1 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 lessened in that Dean is [[DoNoTauntCthulhu nearly tortured to death]] right after, it's still satisfying to see someone finally get to Azazel.]]

--> [[spoiler: '''Dean:''' [[AndThisIsFor That was for our mom]]...you son of a bitch.]]

** Abaddon: She was one of the evilest and most egotistical demons in the series whose lethal brutality was rivalled by few, so when [[spoiler:Dean manages to overpower her, wiping the smug smile from her face as he finally kills her with the First Blade, watching him go AxCrazy on her corpse is somewhat cathartic as the cruel demon is finally dead but by that point, Dean was just [[PummelingTheCorpse stabbing an empty vessel]] and was falling further under the corrupting effects of the Mark of Cain]], thus the moment is almost subverted.
** Lucifer: Okay, let's be honest here. [[spoiler: His death]] in "Let the Good Times Roll" is made of this trope, as we finally see him pay for all the trouble he's caused for Sam and Dean [[spoiler:and their feud with him has finally reached an end after plaguing them for their whole lives.]]
** God: When the ever cruel deity is [[spoiler:[[DePower stripped of all His power and immortality]] by Jack and condemned to grow old, [[GodIsDead die]], and be remembered by no one]], it feels extremely fitting, given all the [[spoiler:[[OmnicidalManiac cosmic havoc He wreaked]], lives He ruined/erased, and manipulation and torment He levied against the Winchesters]]; He faces the punishments He fears the most, and those are [[spoiler:to walk in the shoes of what he saw as his own failed creation and to never be worshipped again]].

** Sam has [[https://66.media.tumblr.com/0d0f04cc5c93f2d56e3069a681c1171f/tumblr_psn3ihtgbR1sggukyo1_400.gifv a particular look of disapproval]] (usually directed at Dean) that fans call his "bitchface". The expression is never named or described in the show proper, but the script for "Nightmare" calls it "a dry 'fuck you' look".
** After "Despair" aired, fans annoyed by [[spoiler: the BuryYourGays treatment given to Castiel]] took to jokingly calling The Empty "Super Hell", "Ultra Hell", "Mega Hell", "Turbo Hell", or [[BreadEggsBreadedEggs "Super Ultra Mega Turbo Hell"]].

* RonTheDeathEater: While John Winchester was not a good parent in canon, fanfics have a tendency to make him even worse, amping up the emotional abuse well beyond what was shown in canon and adding physical abuse as well, even though Sam in "Nightmare" was explicit that John was not physically abusive.

** While not really ''hated'', Lilith is usually seen as inferior to Azazel in the role of "BigBad who wants to free Lucifer", mainly because she lacks the menace, charisma, and personal villainy towards the Winchester siblings that Azazel had. There's also the fact that she usually takes on little girls as her hosts, which, while occasionally genuinely creepy, means that some scenes intended to be NightmareFuel can be hit-or-miss depending on whether or not one finds the child actresses' performances scary.

* LoveToHate: ''Zachariah''. He's a {{Jerkass}} of the highest order and a massive SmugSnake, although he tends to be seen as one of the show's best antagonists due to how punchable he is.

* LoveToHate: Many antagonists count: Meg, Azazel, Gordon, [[EveryoneCallsHimBarkeep the Crossroads Demon]], and Henriksen in the early seasons, to be joined later by Lilith, Uriel, Alastair, Zachariah, and Lucifer. Around Season 8, Crowley, Abaddon, Naomi, and arguably Metatron are added to the roster of LoveToHate villains. According to Sera Gamble, Bela was intended to be an example of this trope in early Season 3, but just about everybody just found the character to be a major annoyance they wanted her off the screen ASAP rather than an enjoyable villain.

* CharacterPerceptionEvolution: 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.

* SacredCow: Seasons 1-5, Creator/EricKripke's tenure as showrunner, are pretty universally agreed to be the golden age of the series, with everything afterwards being deemed [[AudienceAlienatingEra inferior]]. Therefore, saying that any of the first five seasons are bad or—even worse—saying that the later seasons are better is considered a ''horrible'' sin.

Therefore, saying the first five seasons are bad or—even worse—saying that the later seasons are better is considered anathema amongst the fandom.

** [[TheOtherDarrin The second Ruby]] (as played by Creator/GenevievePadalecki). Fans hated her from the get-go, much preferring Creator/KatieCassidy's version of the character, but Kripke believed that with enough time and characterization, fans would like her. Towards the end of Season 3, it appeared to be working, but the final reaction in light of TheReveal [[spoiler:(namely, that Ruby was EvilAllAlong, complete with [[EvilGloating gloating]])]] was ''overwhelmingly'' negative, and fans were just happy she was ''finally'' gone.

** If having hundreds to thousands of monsters killed, even harmless ones, including human psychics, out of [[AbsoluteXenophobe absolute discrimination towards them]] wasn't enough, [[ANaziByAnyOtherName Doctor Hess]] crosses it when she has Ketch kill Mick Davies when he sides with the Winchesters, and is revealed to have crossed it decades before when she ordered student Mick and his friend Timothy to kill each other to prove that they would "execute orders '''without''' question".

** If causing the fall of the angels and blaming it on Castiel wasn't enough, [[ManipulativeBastard Metatron]] ultimately crosses the line when he orders Gadreel to [[WouldHurtAChild kill Kevin Tran, an sympathetic teenager,]] which hurts Dean so bad he considers killing Sam just so Gadreel dies. Metatron even crosses it when he [[HeroKiller kills Dean]] in front of Sam, resulting in Dean coming back as a violent & sadistic demon.
