YMMV: Grimm

  • Aborted Arc: Many fans are beginning to complain about the number of loose ends - such as the primary MacGuffin of the keys, the coins of Zakynthos, Nick's after-effects of being attacked by Baron Samedi, etc, all pushed aside in favor of Adalind's baby, Diana, which has not been as well received a plot point.
  • Alternative Character Interpretation: Prince Viktor. At first glance, he seems to merely be a Replacement Goldfish for cruel and sadistic Eric, but a close examination proves the two very different. Yes, Viktor is ruthless and will do away with those who have 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 doesn't relish it), while Eric would have had him flogged until his skin was falling off and 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.
  • Arc Fatigue: The amnesia storyline, which was finally resolved at the end of season 2. Monroe went on to apologize for it during season 3.
  • Author's Saving Throw: 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 Vocal Minority within the fandom that 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.
  • Big Lipped Alligator Moment: So far, Renard's nightmare about Juliette appearing in his bedroom and turning into a hag in "Nameless" has yet to be explained or even referred to.
    • Explained. In the fourth season, Juliette has transformed into a Hexenbiest.
  • Broken Base: 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, annoying Mary Sue.
    • Juliette is also an example of this especially after her behavior during the Season 3 finale and after.
  • Creator's Pet: Adalind Schade. She seems to exist for no other reason than causing unnecessary drama in the other characters' lives. David Greenwalt has gone on record about how much he adores her...more than one fan has already stated that he's probably the only one.
    • Indeed, some are saying that the show's current arc of Juliette's Face-Heel Turn (and subsequent obsessive desire to murder Adalind for causing it) was written simply to try to garner sympathy for Adalind.
  • Complete Monster: Oleg Stark from season 1's "Game Ogre" is an especially violent Siegbarste or ogre. A hitman for hire, Stark was arrested for a series of brutal murders and escapes jail years later to enact revenge, beating his guards into a coma. Stark hunts down and kills his lawyer, cutting out her tongue, as well as the jury foreman and the judge. The police find the judge's corpse with Stark having stuffed his gavel down his throat. Stark tries to kill the detective who arrested him by blowing up his apartment and when this fails, hospitalizes his best friend Nick to get his location. Even by the standards of the occasionally monstrous beings in Grimm called Wesen, Stark is known as an utter beast.
  • Dropped a Bridge on Him: Kelly. The ultimate Grimm badass is jumped off screen, beaten and decapitated without a fight.
  • Ensemble Darkhorse:
    • Sergeant Wu. Deadpan Snarker and never blinks an eye at Nick and Hank's Wesen reactions. His bad reaction to seeing a Wesen for the first time was heartbreaking for most fans, and Nick and the crew's strange inability to tell him what he saw has sparked some intense rage. No one can deny there's a lot of love for this character.
    • Adorkable Bud, the Wesen repairman.
    • Sebastien, Renard's confidant. He's even got his own fan club - Team Silly Squirrel! (And they've nicknamed him Chirpy - it was originally "Renard's Canary", but "devolved".) They even pulled a "If Sebastien dies, we riot!" movement on Twitter and Tumblr. Sadly, Sebastien died anyways.
    • Meisner, owing to the fact that Damien Puckler is dead sexy and a total Bad Ass. One (female) reviewer has taken to calling him "Tall, Dark and Dreamy".
      • He's got his own fan club as well - "Meisner's Army" or "Puckler's Army".
  • Evil Is Sexy: Adalind and Renard (well, not when Adalind's in her Hexenbiest form).
    • And Renard's Wesen form turns out to be even more hideous.
    • Also Ariel the firedancer, and 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.
  • Fan-Preferred Couple: Adalind/Meisner, after the whole baby Diana arc.
  • Fanon: Lots of fans think that Monroe's full name is "Eddie Monroe" but Word of God says that's never been the case. As of "The Wild Hunt" his parents are using Monroe as his given name.
  • Genius Bonus: More like paying attention bonus, but Monroe brings up during Season 2 that he found his grandmother's antique picnic basket. What kind of Wesen is Monroe again, and what well-known fairytale did one of those and someone with a basket feature in?
  • Growing the Beard: As with all series there is some debate about when exactly this happened but "Game Ogre" is a good candidate. It had the first truly threatening Monster of the Week, foreshadowing some of the tough Hero Killer monsters that Nick would face in the second half of the season. It also added character depth to two previously unpopular characters, one of whom (Juliette) went from the Satellite Love Interest of early season 1 to the cool-headed, Sugar and Ice Personality Action Survivor of the second half almost in the space of one episode (one scene really).
  • Harsher in Hindsight: While Bitsie Tulloch has announced publicly that she and David Giuntoli are in a serious relationship. Now considering what happens in the fourth season.
  • Hilarious in Hindsight: This isn't the only time Dee Wallace has been a werewolf creature.
  • Ho Yay: Good grief. There's Nick/Monroe, Monroe/Roddy, Nick/Renard...
    • Even if you just appreciate the epic Nick/Monroe bromance (Monbromance?)... you might say it's Guy Love, Between Two Guys...
    • Nick calls Rosalee when he needs help with a Wesen medical issue. Monroe is jealous that Nick didn't call him.
    • When Nick and Monroe are talking about how they have to lie about their entire friendship to Juliette, it sounds more like they're talking about covering up an affair rather than hiding their supernatural natures.
    • In "Kiss of the Muse" Monroe and Nick are awfully homey. Then Monroe gets all upset because Nick bailed on dinner with him to go talk to Juliette, and didn't tell Monroe he wouldn't be home.
    • Then, these photos were tweeted...
    • When Nick walks in on Juliette hugging Hank: "Whoa, whoa, whoa! He's mine."
    • There's a mild undertone of Renard/Meisner and Renard/Sebastien (which is amusing when one of them seemingly gets jealous when Renard pays attention to the other - Meisner glares and puffs up, and Sebastien pulls out the puppy-dog eyes).
  • Jerkass Woobie: Captain Renard. He was born the son of a King to a Hexenbiest mother, ostracized from the rest of his family. Then when his stepmother the Queen found out that he was a Zauberbiest, she tried to have both him and his mother killed. They escaped to America, where he ended up as a cop. His family (especially his brother) has tried to kill him more than once. And that was before the business with Juliette and the Zaubertrank. That was when the Sanity Slippage started, forcing him to reveal himself to Nick. That same Sanity Slippage also led to him being seduced by Adalind which led her to becoming pregnant, most likely. Then he finds out he's a father, and then has to give up his child forever.
  • Magnificent Bastard: Captain Renard. He gets a rather amusing line in one episode where he deadpans "Yes, I am Royal, and yes, I can be a bastard."
    • Adalind likes to think she is one, but events tend to prove otherwise.
    • Viktor Beckendorf is slowly outdoing all previous candidates. He appears to be far more competent than his predecessor Eric, being very capable of thinking on his toes. He very handily tricked Adalind into depowering Nick, seemingly coming up with the scheme on the spot when she called him. Even better, once she fulfills his wishes she shows up unexpectedly at Viktor's castle. He had no idea she was coming, but he doesn't even blink before sweet-talking her into going into a hexenbiest-proof prison. Once she's there, he employs a very effective method to bend her to his wishes. Once he gets Adalind talking, it doesn't take him a minute to figure out Kelly Burkhardt has Diana.
    • Prince Kenneth effortlessly lays the moves on Juliette, exploiting her new-found Hexenbiest temper and causing a full-on Face-Heel Turn. In his second episode.
      • Then he masterminds the plan to recapture Diana, which not only works, but more than completes Juliette's Face-Heel-Turn and gets Kelly Burkhardt killed.
  • Moral Event Horizon: Adalind went screaming right into the event horizon during the Season 3 finale, raping Nick and taking away his powers as a Grimm while disguised as Juliette. To make matters worse, she purposefully brought up the past issue of Renard and Juliette's obsession curse and tried to confuse their feelings merely out of spite. This, however, may pale in comparison to...
    • Juliette after turning into a Hexenbiest. In short, 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.
      • 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 in the following episode.
  • Narm: In "Leave It to Beavers", the main villain is a menacing troll Wesen...who would probably be a lot more menacing if he didn't have a rather frightful Speech Impediment
    "My great-uncle was a 'weaper'."
    • When Adalind meets Frau Pech, probably intended, at least for the weirdness.
    Frau Pech: I knew your mother well.
    Adalind: Me too.
    • Although, the tone of conversation suggested that Adalind was really not sorry to see her mother go and really wanted Frau Pech to stop talking about it.
    • 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.
      • It's even more egregious now that part of the show is set in Austria - some of the guest stars are absolutely horrendous (and there are complaints about Sasha Roiz unconsciously adopting the accent of whoever he's speaking to).
      • Possibly handwaved by how we don't know how much time Renard spent in Austria. He went to school in Switzerland (where, apart from German, French and Italian are also spoken) and his mother is French-speaking. It makes sense that French is his stronger language. Also note that he and his brother spoke to each other in French, not German.
      • A scene in "Blond Ambition" has Renard reading one of Adalind's spellbooks (in German) and having to read out loud each sentence in German before translating into English, implying that he's not actually fluent.
    • Nick's nightmare about Monroe and Rosalee's wedding. Supposed to be very creepy, it provokes more laughs than terror.
    • When Sebastien is interrogated, he is subjected to the cruelest torture of all...waterboarding. One is half-expecting Viktor to call for the comfy chair next. Not that waterboarding isn't a grueling ordeal, but hardly the first thing one comes up with when thinking of Cold-Blooded Torture.
      • Only if one's never been subjected to it. Done right, it inflicts no physical damage, but is so traumatic that it can break a subject right out of the gate. Even if it doesn't, the lack of physical damage means the subject's unlikely to die before you get to the fancier methods, if they're necessary.
      • Still more humane than getting your skin flogged off, though.
    • The entirety of Adalind's Mind Screw in the castle, especially if you don't sympathize with her. It's quite out of the blue and the method used is never truly explained.
    • At the end of "Dyin' On A Prayer", there's a dramatic cliffhanger as everybody stares at Juliet, who says "What?" Only problem is, Bitsie Tulloch's lazy eye is very evident in this shot, making her look very odd, and her "What?" sounds weird and out of place in an otherwise serious scene.
    • The ridiculous demonic arms that come out of Renard's mirror and try to grab him.
    • Nick's three no's at the end of Headache. There's actually five, but the first two were fairly well done. It's just the last three that the audience hears while staring at his house that sound a little ridiculous.
  • Nice Job Breaking It, Hero: Even though Renard's mother brought her son back to life and restored Nick's powers, it can be argued that both of those plans backfired horribly. Renard suffered from sporadic bleeding, blackouts and was possessed by a serial killer while Juliette turned into a Hexenbiest, began working for the Royals and ultimately helped them secure Adalind's daughter while getting Nick's mother and then herself killed.
  • One-Scene Wonder: Many side-characters like Hap, Roddy, Barry, Holly, and Bud The Fridge Repairman (before he was promoted to a recurring character) have gained following.
    • 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 Genre Savvy things like 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.
  • Rescued from the Scrappy Heap: The episode "Game Ogre" has been termed "The Episode Where No-one is Useless" in which Hank Griffin and Juliette Silverton, previously somewhat bland characters, both get a bit more depth of character.
    • This sticks hard for Juliette, and not so much for Hank (at first). Although Juliette ultimately went back to Scrappy territory in Season 4. Actually, while many people love it, some people are complaining about the amnesia storyline, and, despite her good amount of fan love, some people are claiming Bitsie Tulloch is the weakest cast member.
      • She's skidded right back into Scrappy territory as of mid season four, with many fans clamoring for her death (preferably by Nick's hands). She is indeed killed, but by Trubel pulling a Big Damn Heroes moment when Juliette has Nick cornered.
    • Finally achieved for Hank "One Punch" Griffin in in Bad Moon Rising when he goes from freaking out over finding out about the Wesen - and that his goddaughter and best friend are one - to dropping a Coyotl (in full game face, no less) in one punch!
    • As of 2x12, Hank is a quietly beloved character who wormed a little place in the heart of almost all fans, and gains a lot of sympathy while Juliette is in Base Breaker territory, to the point of almost creating a gigantic Flame War. She was first showcased in this show as a sweet, well-balanced but Satellite Love Interest who risked to become a Damsel in Distress, and whom the fans found boring, but was revealed to be a Properly Paranoid Action Girl with an aloof side who wants to be accepted as an independent person and be a part of the most recent events, and, while still sweet, she may or may not exhibit signs of Never My Fault and makes Nick The Scapegoat for their failed relationship.
  • Romantic Plot Tumor: The Nick-Juliet-Renard love triangle could be seen as this until season 2 episode 13, when it becomes Fridge Brilliance by resolving that plot while developing another.
  • Ron the Death Eater: It seems that no matter what Juliette does, no matter how much stronger she gets, no matter how much 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. They got their wish in the Season 4 finale after Juliette became a powerful and vicious Hexenbiest and crossed the Moral Event Horizon.
    • There are some who wish Nick would just get out of the Bauerschwein's way and let them get about exterminating the Blutbaden once and for all... no matter how many normal, well-adjusted people that means killing in the process.
  • The Scrappy: Adalind, for some time until the penultimate episode she appeared in in season 1 showed that she had a Stage Mom and was a Love Martyr to Renard. That, Renard's Manipulative Bastard-ness and her elegant and carefully-thought revenge increased her popularity for a while. However, her vile intentions and careless actions towards her own unborn child began to drag her back to this status. She seems to suffer from an endless supply of stupidity and her monster baby storyline dragged out almost interminably, taking time away from the main storyline in Portland. And now that she's pretty much crossed the line by raping and depowering Nick in the Season 3 finale, she has fallen back into Scrappy status. 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 necessitated by Adalind's actress, Claire Coffee, becoming pregnant in real life).
    • Juliette's been wavering in and out of this trope, but seems to have been rescued from it, albeit in a special way. Sadly, she fell back into Scrappy territory in Season 4, and her behavior as a Hexenbiest ultimately fulfills Nick's greatest fear, the reason why Aunt Marie told him to break up with her in the series premiere: She is killed in the Season 4 finale.
  • Ships That Pass in the Night: Roddy Geiger ("Danse Macabre") and Barry Rabe ("Bears Will Be Bears") are frequently shipped together, presumably because they are in the same age group, despite the fact that they have most likely never met. And both of them tend to get shipped with Holly Clark ("Let Your Hair Down") for roughly the same reasons.
  • Special Effects Failure: The Volcanalis from "Ring of Fire." When he's on fire, the CG is painfully obvious, especially when little globules of lava fly off his body.
    • The actress playing "Mrs. Garcia" in "El Cucuy" is 54. Mrs. Garcia is 77, and the costuming department thought that the way they could age her up was giving her a ridiculous, cheap-looking wig. It looks worse in the episode - it looks unnatural and you can almost see where the wig ends and her real hair begins! This can behandwaved in that old age effects are among the most difficult to pull off (although they could have at least fitted the wig properly). And that said, much like La Llorona and Volcanalis, El Cucuy is presented or heavily implied to be extremely long lived. So while she may be 77 years old, it may not mean as much to her species as it does to other Wesen and humans.
  • Squick:The less said about the frogs in "Lonelyhearts", the better. Or the rats in "Danse Macabre" who chewed off a man's face. Or the judge with a gavel shoved down his throat and the woman with her tongue cut out in "Game Ogre".
    • How Spinnetods kill their victims.
    • Not as bad as some other examples, but two words: Blood. Cookies.
    • What happens to Wu’s face in “Island Of Dreams”.
    • Basically, if you're going to get killed by a Wesen who isn't concerned about The Masquerade at the moment or you're bumping into a Wesen engaged in some of the more instinctual habits... it's probably not going to particularly nice.
    • What Geiers are infamous for as a species - brutally harvesting human organs from victims that are still alive, be they wounded soldiers on the battlefield or homeless kids on the streets - and selling them on a Wesen black market that uses the parts like apothecary ingredients.
    • The Lowen underground gladiator ring feeding new contestants the remains of defeated fighters.
    • Let's also not forget how traditional Coyotl families "introduce" seventeen-year old female members to the pack. Which is not an introduction and just a way to sugar-coat gang-rape and incest.
    • Also in "To Protect and Serve", Nick falls into a pit of decomposed corpses. When trying to find his flashlight, he accidentally grabs rotten body parts.
    • In "Mr. Sandman" we get the image of a parasitic worm wriggling out of a persons bloody eye socket. Sleep well.
    • A pregnant Gluhenvolk's "pickles and ice cream" is apparently raw cow ovaries. Yum.
    • Adalind's trials to get her powers back might be amusing given Adalind's discomfort but they truly are disgusting.
    • The hideous fate of Blutbaden who ate the "Black Despair" mushrooms in "Best Served Cold". Their helplessness and hopelessness are as horrible as their agony.
  • Tastes Like Diabetes: 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 Game Face and attacks.
  • Tear Jerker: Angelina's death and Monroe's grieving for her.
  • Too Cool to Live:
    • Aunt Marie. Badass to the end (of the second episode).
    • Also Angelina.
    • And now Kelly as well.
    • As of the Season 4 finale, Juliette becomes the first main cast character to die.
  • Vanilla Protagonist: Some fans consider Nick's vanilla characterization to be a strength of the show, since it is a nice reprieve from all the "special" or "tortured" protagonists which are especially common in Genre show. Nick being a normal boring person who deals with his new abilities without a lot of drama is one of the aspects which sets the show apart.
  • What an Idiot: Adalind comes under this so often it's practically gotten to the point of Once per Episode. It wasn't such a good idea for her to be letting so many people know she was carrying Royal blood. Or for her to to trust 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 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, she tries out newly discovered telekinetic powers. You know, two seconds after she's made aware someone is watching her. When 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 an Express Delivery, 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.
    • And then 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 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 all a nightmare that was inflicted on her by Viktor.
    • It apparently never crossed her mind that sleeping with Nick could get her pregnant with his child. Leave it to Adalind to turn a Moral Event Horizon into another Epic Fail.
    • Then she attempts to explain her pregnancy to Prince Kenneth by claiming that she is pregnant with Viktor's child. Then Kenneth reveals that Viktor is sterile, and it doesn't take him long after that to realize that Nick's the father. At this point, Adalind might as well be the face of Epic Fail.
    • Nick isn't immune. In "Marachausee", he comes home to find 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.
  • The Woobie:
    • Nick gets put through the wringer repeatedly throughout the series.
      • Seasons One and Two: He proposes to Juliette, she turns him down because she can tell he’s keeping secrets from her. Of course, he’s keeping secrets to protect her from the crazy dangerous stuff that he now has to handle. When he finally tells her, she doesn't believe him. It takes all of Season Two for things to be made right between them. However, with his new powers coming into play Nick was getting less pitiful and more of a threat.
      • Season Three: He loses his powers after being deceptively raped by Adalind.
      • Season Four: He regains his powers but the act of doing so turns Juliette into a Hexenbiest. This causes an irreparable split in their relationship as Juliette partly blames him for what happened to her and this directly leads to the deaths of Kelly Burkhardt and Juliette herself, the two of the most important women in his life.
    • Hap, the friendly Blutbad in "Three Bad Wolves" who gets killed over a blood feud he was never personally involved in.
    • Monroe is a Blutbad who lives apart from his family, likely because he has a vegan lifestyle while they still hunt. In "Three Bad Wolves" he gets caught between looking for vengeance of his friend's death and staying out of the fight to avoid escalating things to worse levels... even though that means his former lover may end up dead. Things go great for him for a while but now stands in danger of being disowned from his family altogether for loving a Fuchsbau.
    • Rosalee. She grew up different because she is Wesen. She pursued the wrong crowds to feel like she belonged. She ended up getting addicted to drugs and landing in jail, unknowingly missing out on her own father's funeral. She loses her brother to an armed robbery. Then she finally meets Monroe and everything is fine...for a while. She even manages to get reconciled to her mother and sister. But then she meets Monroe's parents. They turn out to be species purists who refuse to give their blessing to the relationship and Rosalee leaves the house in tears.
    • Sebastien. Worked as Renard's spy in the castle, was captured, tortured and beaten to within an inch of his life (and as a result was forced to betray Meisner and Adalind), manages to ambush his captors, but ends up being shot and killed by Viktor after he ran out of bullets.
