History YMMV / Grimm

* UnintentionallyUnsympathetic: The entire cast of protagonists become this when they [[spoiler: conspire to steal Adalind's baby from her]]. The episode before, Nick immediately decides that [[spoiler: Adalind wasn't going to be a good mother to Diana, and worse, Kelly compares it to her choice to give up a life with Nick, saying that sacrificing what we love most is what we have to do... save that Adalind ''never made that choice'', and they ''forced it on her''. Made worse when Nick unsympathetically reaffirms his belief that Adalind wasn't going to be a good mother after she came desperately crying to them for help.]]

** Many guest Wesen characters like easygoing, non-martial Blutbad Hap, Reinigen ScholarshipStudent Roddy, Barry (the Jagebar whose mother has him ready to start HuntingTheMostDangerousGame), tough but vulnerable Blutbad WildChild Holly, Fuschbau RebelLeader Ian Harmon, vengeful Balam detective Valentina, CuteMute Naidad Elly, unwilling PoisonousPerson Folterseele Bella, alluring ManipulativeBitch Ariel Eberhart (a Damonfuerer), KnightTemplar El Cucy, and LovableCoward Eisbiber Bud The Fridge Repairman (even before he was promoted to a recurring character) have gained decent followings.

* OneSceneWonder: Many guest characters like easygoing, non-martial Blutbad Hap, ScholarshipStudent Roddy, HuntingTheMostDangerousGame Barry, tough but vulnerable WildChild Holly, and Bud The Fridge Repairman (even before he was promoted to a recurring character) have gained decent followings.
** Valentina Espinosa and Ian Harmon were nowhere near them, but in way of growing into it.
** Casey, a would-be victim in "Mr. Sandman". She actually does some pretty savvy things like [[spoiler: covering her eyes against a Wesen that targets them when he attacks her, gets a weapon as soon as she's able to, and ultimately is the one to defeat the wesen of the week.]]

* OneSceneWonder: Many side-characters like Hap, Roddy, Barry, Holly, and Bud The Fridge Repairman (before he was promoted to a recurring character) have gained following.

* EvilIsSexy: Adalind and Renard (well, not when Adalind's in her Hexenbiest form).
** And [[spoiler: Renard's Wesen form turns out to be even more hideous.]]
** Also [[spoiler: [[DraconicHumanoid Ariel the firedancer]], and [[BitchInSheepsClothing Lucinda]].]]
** Eric Renard is quite dashing, when he's not having people tortured or killed.
** Khloe Sedgwick, the Musai from "Kiss of the Muse," professes that what the men who fall in love with her do (obsession with her, violent rage towards any challengers for her love) is not her fault, but over the course of the episode it becomes clear she both encourages it and seems to enjoy watching it.

* RonTheDeathEater: It seems that no matter what Juliette does, no matter how much [[TookALevelInBadass stronger she gets,]] no matter how much [[WomenAreWiser help and advice she gives Nick,]] some fans will never be satisfied with her and find any and every reason to belittle her and even want her dead. [[spoiler: They got their wish in the Season 4 finale after Juliette became a powerful and vicious Hexenbiest and crossed the MoralEventHorizon.]]

* TheScrappy: Adalind, who managed to become one of the good recent examples of what to do to fall into the trope. For some time [[spoiler: until the penultimate episode she appeared in season 1 showed that she had a StageMom and was a LoveMartyr to Renard]]. [[spoiler: That, Renard's ManipulativeBastard-ness and her elegant and carefully-thought revenge increased her popularity for a while]]. However, her vile intentions and careless actions towards [[spoiler: her own unborn child]] began to drag her back to this status. She seems to suffer from an [[IdiotBall endless supply of stupidity]] and her [[spoiler: monster baby]] storyline [[ArcFatigue dragged out almost interminably,]] taking time away from the main storyline in Portland. And now that she's pretty much [[MoralEventHorizon crossed the line]] by [[spoiler: raping and depowering Nick]] in the Season 3 finale, she has fallen back into [[TheScrappy Scrappy]] status. [[spoiler: The news that she's likely pregnant with either Nick or Renard's baby already has many fans screaming bloody murder (this plot point, however was [[RealLifeWritesThePlot necessitated by Adalind's actress, Claire Coffee, becoming pregnant in real life).]]]] This is ironically not the first series with a serious Scrappy problem that showrunner David Greenwalt (who "adored" the character) has been involved in; he was also involved with ''Series/{{Angel}}'' during the reign of another infamous {{Scrappy}}, Connor (both Connor and his Joss Whedon/''Buffy'' predecessor Dawn were listed in the 2004 book ''Literature/WhatWereTheyThinkingThe100DumbestEventsInTelevisionHistory''; said book [[Franchise/ScoobyDoo includes the]] TropeNamer).

** Juliette's been wavering in and out of this trope, but seems to have been rescued from it, [[BaseBreakingCharacter albeit in a special way]]. [[spoiler:Sadly, she fell back into Scrappy territory in Season 4, and her killing Nick's mother and burning down the trailer has made her possibly the most hated character on the show.]]

* UnintentionallyUnsympathetic: The entire cast of protagonists become this when they [[spoiler: conspire to steal Adalind's baby from her]]. The episode before, Nick immediately decides that [[spoiler: Adalind wasn't going to be a good mother to Diana, and worse, Kelly compares it to her choice to give up a life with Nick, saying that sacrificing what we love most is what we have to do...save that Adalind ''never made that choice'', and they ''forced it on her''. Made worse when Nick unsympathetically reaffirms his belief that Adalind wasn't going to be a good mother after she came desperately crying to them for help.]]

** [[spoiler: Juliette after turning into a Hexenbiest.]] In short, [[spoiler:she sides with Kenneth, burns the trailer, and a recent episode ended with her using her powers to cause Nick to point a gun at Monroe and actually shoot at him, failing because Hank managed to tackle Monroe out of the way at the last second.]] She's so far past the horizon that's she at the bottom of it.
*** [[spoiler: And right before the season finale, she's part of a plan to lure Nick's mother, Kelly, into his house to take Adalind's daughter from her and have Kelly killed. Nick, Hank and Trubel find her decapitated head inside a box at the end of the episode, and at this point pretty much everybody wants to see her dead, and she is indeed killed (temporarily) in the following episode]].

** When Adalind meets Frau Pech, probably intended, at least for the weirdness.
--> '''Frau Pech''': I knew your mother well.
--> '''Adalind''': Me too.
** Each and every time Captain Renard speaks German. The man grew up in Austria, you'd expect him to get the syntax right, at least. Same goes for most other instances of characters speaking German, although Monroe is excused for being a third generation immigrant.

** Adalind Schade. Those who dislike her tend to cite her rape of Nick, CreatorsPet tendencies and multiple moments where she seemed to have superglued the IdiotBall to her person (for example, sleeping with various characters and then being surprised when she gets pregnant.) Her fans argue that Nick himself didn't view the act as rape, and bring up the fact that not only was Adalind [[MamaBear acting out of desperation and doing everything she could to get her child back]], Nick arguably sexually assaulted Adalind himself by kissing her to get her to bite him when he depowered her.
** Juliette, Juliette, ''Juliette''. Victim of bad writing who was turned into [[RonTheDeathEater Juliette the Hexenbiest]] in order to get her out of the way for Nick/Adalind to happen, or a badly acted mess who deserved everything she had coming to her? You decide! Interestingly fan opinion has softened on Juliette in the years after the show went off the air, with many former detractors switching to the initial camp and saying both the actress and the character were poorly treated by the writers.

** A mild example with the addition of Theresa "Trubel" Rubel to the cast. Some feel she's a welcome breath of fresh air into the cast, and others feel she's an unnecessary and annoying.

* AlternativeCharacterInterpretation: Prince Viktor. At first glance, he seems to merely be a ReplacementGoldfish for [[TheCaligula cruel and sadistic Eric,]] but a close examination proves the two very different. Yes, Viktor is ruthless and will do away with those [[YouHaveOutlivedYourUsefulness who have]] [[YouHaveFailedMe failed him,]] as is apparently typical for his kind. But then we find out his desire to find Eric's killer and get a hold of Diana does not stem from personal ambition, but from his uncle threatening to kill him if he doesn't. His examination of Sebastien is vastly different from the way Eric would have handled things. Viktor has him waterboarded and punched and doesn't even watch closely (suggesting he [[IDidWhatIHadToDo doesn't relish it]]), while Eric would have had him flogged until his skin was falling off and [[ForTheEvulz Eric would have enjoyed every second.]] While Viktor ''did'' give the FBI agent leave to kill Captain Renard (who, as far as he is concerned, is a known traitor), for his part he was willing to leave everyone in Portland alone in exchange for Diana, showing that he ''was'' slightly reasonable.

** The amnesia storyline, which was finally resolved at the end of season 2. Monroe went on to [[LeaningOnTheFourthWall apologize for it]] during season 3.
** Adalind's baby, both times. The first dragged on for the entirety of season while almost never actually progressing, and the second not only represented the vanguard of an extremely controversial AudienceAlienatingEra that divided the fanbase right up to the end of the show, but itself dragged on forever clogging up the lives of various characters with unnecessary drama.

** Adalind's baby.

** Juliette, Juliette, ''Juliette''. Victim of bad writing who was turned into [[RonTheDeathEater Juliette the Hexenbiest]] in order to get her out of the way for Nick/Adalind to happen, or a badly acted mess who deserved everything she had coming to her? You decide!

* DorkAge: The fourth season due to overfocusing on the baby Diana storyline and Adalind storyline and characterization while completely excluding the other major plotlines except for the Season 4-only Wesenrein after fans had already voiced disapproval with the arc. This was after the infamous final episode of Season 3, and the whole obsession with Adalind finally did lead to a small drop in ratings in the season, and prompted a different team to write the Season 4 finale and Season 5 premiere than the previous premieres/finales; these episodes also [[spoiler:saw the elimination of the original version of Creator/ElizabethTulloch's character through killing her after she crossed the MoralEventHorizon and dropped back into Scrappy status (she CameBackWrong later in the season), and eliminated Adalind's Hexenbiest powers on her own volition and gave her some badly-needed CharacterDevelopment.]]

* AuthorsSavingThrow: The handling of the Blutbaden/Bauerschwein feud in its introductory episode wasn't bad, but it was... ungraceful. While attempting to portray the bad blood between the two races at least somewhat evenhandedly, the Bauerschwein definitely came off as the more-sympathetic of the two, creating a VocalMinority within the fandom that [[RonTheDeathEater tarred every Blutbad with the same brush as Angelina]]. "Trial by Fire" revisited the events of that episode, with Nick openly admitting that he was young, inexperienced, and mostly-ignorant of the details at the time and isn't sure how he'd handle it now. Peter Orson, meanwhile, is permitted a measure of personal redemption, and Monroe, while still refusing to forgive him for the vigilante murder of Hap, an innocent man, ultimately comes to terms with the motivations that prompted his actions.

*** Other fans found it reprehensible for a show to turn a character's rapist into their true love regardless, as it sends a rather [[UnfortunateImplications terrible message]].

** Other fans find it reprehensible for a show to turn a character's rapist into their true love regardless, and that it sends a terrible message.

* SpiritualSuccessor: to ''Series/{{Angel}}'' and ''Series/BuffyTheVampireSlayer''. Not much of a surprise, considering all three had David Greenwalt as a producer. ''Grimm'' was kind of a hybrid of both shows, as if the Chosen One of the Slayer took on cases involving the supernatural like Angel. In a neat sequence, Buffy mostly focused on teenage years, Angel focused on a lot of 20-somethings, and many of the characters of Grimm are in their 30s.

** A strange example with Adalind. As the show's TheScrappy, people latched onto her [[spoiler: disguising herself as Juliette to have sex with him to strip him of his powers]] as something she did ForTheEvulz, even though the only reason she did that was because [[spoiler: she incorrectly thought the Royals had Diana, and when she called in her desperation to get her back, they told her she could do this in exchange for getting Diana back.]] Most entries on Wiki/ThisVeryWiki tend to leave that part out.

* FandomRivalry: With ''Series/OnceUponATime''. The only things they have in common is having a fairy tale theme and premiering around the same time, but fans just can't stop comparing the two and arguing which is better. Fans of OUAT dismiss Grimm as either having too much of a slow-moving plot, just being a MonstersOfTheWeek show dressed as a PoliceProcedural one or being a ripoff of ''Series/{{Supernatural}}'', while Grimm fans criticize OUAT as being too [[TastesLikeDiabetes light-hearted, cheesy,]] soapy, Disney-fied and being a "chick show".

* TastesLikeDiabetes: In "The Bottle Imp", the foster family that April is sent to live with have shades of this. The audience is ''not'' surprised when after five minutes of dealing with them, she puts on her GameFace and attacks.

* FanPreferredCouple: While Nick is all but engaged to his live-in girlfriend Juliette and finds a second love in Adalind (who has his son), the fandom loves to pair him off with Monroe instead.

* AuthorsSavingThrow: The handling of the Blutbaden/Bauerschwein feud in its introductory episode wasn't bad, but it was... ungraceful. While attempting to portray the bad blood between the two races at least somewhat evenhandedly, the Bauerschwein definitely came off as the more-sympathetic of the two, creating a VocalMinority within the fandom that [[RonTheDeathEater tarred every Blutbad with the same brush as Angelica]]. "Trial by Fire" revisited the events of that episode, with Nick openly admitting that he was young, inexperienced, and mostly-ignorant of the details at the time and isn't sure how he'd handle it now. Peter Orson, meanwhile, is permitted a measure of personal redemption, and Monroe, while still refusing to forgive him for the vigilante murder of Hap, an innocent man, ultimately comes to terms with the motivations that prompted his actions.
* BrokenBase:

* CriticalResearchFailure: The [[WordOfGod official explanation]] for the [[CallARabbitASmeerp Wesen names]] is that "they made stuff up out of fear that they'd sound like things that actually exist". Essentially being completely upfront about not doing ''any'' research ''at all''.

* HilariousInHindsight: This isn't the only time Creator/DeeWallace has been [[Film/TheHowling a werewolf creature]].

** Adalind Schade. Those who dislike her tend to cite her rape of Nick, CreatorsPet tendencies and multiple moments where she seemed to have superglued the IdiotBall to her person (for example, sleeping with various characters and then being surprised when she gets pregnant, see WhatAnIdiot below). Her fans argue that Nick himself didn't view the act as rape, and bring up the fact that not only was Adalind [[MamaBear acting out of desperation and doing everything she could to get her child back]], Nick arguably sexually assaulted Adalind himself by kissing her to get her to bite him when he depowered her.

* WhatAnIdiot:
** From "Quill", Nick touching a blood-splattered and clearly-infected body with his bare hands. Later on, it's revealed to be not contagious, but he has no way of knowing that after being on the case for all of two minutes.
** Adalind comes under this so often it's practically gotten to the point of OncePerEpisode. It wasn't such a good idea for her to be letting so many people know [[spoiler: she was carrying Royal blood.]] Or for her to to trust [[spoiler: Stefania so completely]] since the latter had already shown backstabbing tendencies. She never even asked Stefania to completely explain it to her; she only blindly follows instructions. Or for her not to think that the Royal Family just might be watching her [[spoiler: when there's a camera inside her room!]] And then shunning and snarking one of the few people who may be able to help her if things go sour. And then when she is in a restaurant and she knows that someone is sitting behind her staring at her, [[spoiler: she tries out newly discovered telekinetic powers.]] You know, two seconds after she's made aware someone is watching her. When [[spoiler: her unborn child begins to kick unnaturally and starts causing her pain]] she waits until she's writhing around in agony before calling Stefania and asking for advice. And when told that she is facing [[spoiler: an ExpressDelivery]], she reacts not with the slightest bit of concern (and again, no prying questions) but with mere ''annoyance.'' In fact it might be easier to list the things she does that ''aren't'' idiotic.
*** In season four, she trusts some random prisoner who gives her food out of a box and then leads her out into a labyrinth without once questioning him. At the end of "Dyin' On A Prayer", this has left her [[spoiler:trapped and in danger of drowning.]] Way to go, Adalind! It gets better in the following episode, where voices keep claiming they have her baby, and she keeps listening to them. At the end of it all, she winds up back in her cell, the whole labyrinth apparently being [[AllJustADream all a nightmare]] that was inflicted on her by Viktor.
*** It apparently never crossed her mind that [[spoiler: sleeping with Nick]] could get her [[spoiler: pregnant with his child.]] Leave it to Adalind to turn a MoralEventHorizon into another EpicFail.
*** Then she attempts to explain her [[spoiler:pregnancy]] to Prince Kenneth by claiming that she [[spoiler:is pregnant with Viktor's child]], which blows up in her face when Kenneth reveals that Viktor is [[spoiler:sterile, and it doesn't take him long after that to realize that Nick's the father.]] [[EpicFail At this point, Adalind might as well be the face of Epic Fail.]]
*** It is at this point, where she hits rock bottom, has her epiphany and [[RescuedFromTheScrappyHeap begins her redemption arc]]. From the moment in that episode where she [[spoiler: walks into Renard's office to reveal her pregnancy]], her characterization changes completely, with her dropping the idiot ball and doing a full HeelFaceTurn.
** Nick isn't immune. In "Marachausee", he comes home to find [[spoiler: a Manticore dead by his own stinger. Juliette was able to kill him with her power. She tells Nick that the professional killer accidentally stabbed himself with his own stinger, the stinger he had used countless times to dispatch victims.]] And... he believes it.

** Other fans find it reprehensible for a show to turn a character's rapist into their true love regardless.
