!!Comic:

* DarknessInducedAudienceApathy: A minor problem with the first six-issue arc of ''ComicBook/IZombie''. Nothing is resolved, the BigBad is a "good" guy who can't be hurt, and the main star has no connection to things going on.

!!Series:
* ArcFatigue: Liv and Major's on again off again relationship has started to bore some fans, much in a similar vein to ''Series/{{Friends}}'''s infamous WillTheyOrWontThey. First they can't be together because Liv is a zombie, and by season 2, Major tries to cut off ties while protecting her from Vaughn which leds them to be together again and breaking off again when Liv tells that Major and her have unsolvable differences now, not only in relation to her being a zombie, but because she changed and he can't accept it, as well as they can't have sex unless they are both zombies or both humans. Even when they are both zombies in season 3, they still decide to not be together while still teased and even sleeping together [[spoiler:when Major has to take the cure]], leading to Liv dating Justin while Major sees other women. It does not help that their RomanticFalseLead are actually very well liked characters such as Lowell and Drake who both get awful fates to guarantee that they can be together even if they won't.
* AuthorsSavingThrow: After months of complaints about Clive never appearing to notice Liv's massive personality swings that match the victims they're working on, "Whopper" finally acknowledges that he ''has'' noticed for a while, simply assuming that it was a result of the "psychic gift" he thinks she has. [[spoiler:Then it becomes irrelevant when he's let in on the truth at the end of the season.]]
* CompleteMonster: [[CorruptCorporateExecutive Vaughn Du Clark]], the BigBad of season 2, was indirectly responsible for the zombie outbreak in the series. When word got out that his drink, Max Rager, had deadly side effects, he covered this up. When he found out about the zombies, he ordered Major to hunt down and kill all known zombies to keep quiet, and threatened to kill Liv if he didn't comply. He tracks down people that give negative feedback on his product, no matter how obscure the review is, Vaughn videotapes himself killing them. At first, it seems that that Vaughn's daughter, Rita, is his MoralityPet, but when a zombie in his custody broke free, he [[spoiler:[[DirtyCoward left Rita for dead]], only for her to become a zombie too]]. As a result, he has her detained for the rest of the season. During the season finale, Vaughn finds out that Major was only hiding the zombies he ordered dead, but was using them as guinea pigs for a potential cure. All of the cure prototypes fail and cause the subjects to become feral. Liv, Major, and [[spoiler:Clive]] manage to infiltrate his secret lab, so he tries unleashing the feral zombies on them. When that fails, he decides to unleash a poisonous gas on them, the remaining sapient zombies, and even [[spoiler:Rita, after claiming to be remorseful for letting her get zombified]]. When Rita tearfully asks if he ever even cared about her, he yells at her for 'making it about her' as he was more concerned with what this would do for his plans to make money rather than the life of his daughter. Unlike Blaine, who got a FreudianExcuse in the form of his abusive childhood and [[spoiler:a couple of PetTheDog moments prior to losing his memory]], Vaughn has ''no'' visible excuse for his actions beyond greed, and [[spoiler:dies a karmic death without any sign of remorse.]]
* CounterpartComparison: During Season 2, Major, the former significant other/love interest of Liv, the main character, develops a drug problem and starts going down a self-destructive path. Two years ago, ''Series/{{Arrow}}'', another DC Comics-based CW show, had Laurel, the former significant other/love interest of Oliver, the main character, developed a drug problem and also went down a self-destructive path. Fortunately for Major, while Laurel's story arc suffered from ArcFatigue and turned her into TheScrappy of the show, Major's story arc wrapped up in less than 5 episodes and he began his recovery. Thanks to better acting/writing/direction, they also avoided making him unwatchable and he instead ended up even more of a Woobie than he already was.
* CrowningMusicOfAwesome:
** Hollow Wood's [[https://www.youtube.com/watch?v=9daymAkdg_U Oh My God]] playing over Liv, under the effects of her old friend who loved to practice extreme sports as she runs through the streets of Seattle in a bike with a rare smile across her face.
** After the Fira's [[https://www.youtube.com/watch?v=vBfFDTPPlaM Der Komissar]] playing over the Meat Cute Mass Murder when Major kills everyone related to Blaine's operation.
** Band of Skulls' [[https://www.youtube.com/watch?v=aAclM2isoRU Sweet Sour]] is perfectly fitting for the scene in season 3 in which Blaine [[spoiler:now no longer feigning amnesia starts plotting the take back of his operation and prepares ravi's blue juice, it really shows old Blaine is back]].
* EarWorm:
** [[https://www.youtube.com/watch?v=E73IQx21DEo Stop running nooooow, I'm already dead...]]
** Major's [[spoiler: RoaringRampageOfRevenge]] in "Blaine's World" is set to [[https://www.youtube.com/watch?v=vBfFDTPPlaM "Der Kommissar"]] by After the Fire, and works perfectly.
* EnsembleDarkhorse: Lowell gained quite a lot of popularity despite being only a RomanticFalseLead, even after his death. His actually rather sweet relationship with Liv and their mutual condition helped make them a FanPreferredCouple.
* EvilIsCool: Blaine does make being an utter bastard look fun. Also crosses into EvilIsSexy as he has more than a few fangirls.
* FanPreferredCouple: Blaine/Liv has a large amount of fans despite the canon leading to Liv/Major and Blaine/Peyton(both of which fell through though).
* FriendlyFandoms: Fans of ''Series/PushingDaisies'' tend to enjoy the show, given they're both light-hearted procedurals with the protagonist using the victims themselves to solve the CaseOfTheWeek. The fact they're both set in a WorldOfPun helps, too.
* HarsherInHindsight: In season 1, Blaine said this his FreudianExcuse was "daddy issues, megalomania, and greed" in a rather sarcastic tone. However, season 2 reveals that [[spoiler: he resents his father because he, among other things, forced his grandfather into a retirement home and had him raised by a horrible maid who regularly abused him]].
* HoYay: There's a bit between Major and Ravi once they move in together.
* IdiosyncraticShipNaming: Ravi/Liv has the rather fun name of Ravioli in the fandom.
* LesYay: There's a good amount in general between Liv and Peyton, highlighted by "Pour Some Sugar, Zombie" where Liv, on stripper brain, gives Peyton a ''lap dance'' and gets irritated when Peyton isn't as into it as she'd like. This gets further pushed in the episode, "Return of the Dead Guy," when discussion about Liv and Justin getting together turns into the below bit, which preceded a scene [[ItMakesSenseInContext with Liv making Peyton dress up as a dominatrix, including spanking Liv which Peyton starts to get really into]].
--> '''Peyton''' Ah... I see why you want the place to yourself. Well, um... What if I can make you a better offer?
--> '''Liv''' I don't want you to be insulted, and don't think I haven't ''considered'' it, but I'm going to stick with men.
** "Brother Can You Spare A Brain" sees Liv momentarily get cozy with a female that she and Clive are questioning, but that's not all.
** "Return of the Dead Guy" takes it to pure PanderingToTheBase levels, as Peyton has to act like a dominatrix to get Liv's current brain to have a vision, and finds herself getting pretty into it.
* JerkassWoobie: Any of the killers that have sympathetic motives. Season 2 reveals that even [[spoiler: Blaine is one]].
** Rita becomes this in "He Blinded Me...With Science!" when [[spoiler:her father [[MoralEventHorizon leaves her to die]] and she gets turned into a zombie. Made even worse when in the finale she realizes her father never truly loved her and only cared about himself.]]
* MagnificentBastard: Blaine becomes the sole supplier of brains to the zombies in the city, operating out of an actual butcher shop, using regular (i.e. not undead) delivery boys. His first act is to have sex with a rich older woman, infecting her, and then offer to supply her with brains for $25,000 a month. He's also charming and disarming, convincing Clive that his shop is on the level, when the detective comes to ask about a dead kid. He even offers Clive to show him around the back of the shop, despite having a cut-up body there ([[spoiler:although, had Clive agreed, he would've been killed]]). Despite being a lowly street dealer when he was alive, Blaine shows refinement, admitting he used to be a wine connoisseur before his taste buds atrophied, and even has his cook try to come up with tasty dishes with brains.
* {{Moe}}: Liv herself, largely due to her short size, PerkyGoth-style appearance, and the effects of many of her brains-of-the-week.
* MoralEventHorizon:
** After first being shown to apparently be willing to leave his old life of drug dealing, once he finds out he can turn ''others'' into zombies and uses this to make a brain-dealing business, Blaine establishes himself as a villain. But what crosses this is when its revealed that his source of brains for his operation is actually troubled teenagers who he kidnaps and kills, rather than his claim of grave digging.
** In season 2, Blaine seems to have at least tried to change, starting a new operation that doesn't kill kids for the brains, and is willing to work with Liv in getting what they need to work on the cure (albiet, for self-preservations purposes). So, to establish he's still a monster, he positions a very scared underling into becoming the face of his Utopium ring, getting the guy and his dealers brutally killed by Blaine's former boss, and is revealed to have zombified ''his own father'', and blackmails him out of a large sum of money. He might be [[spoiler: human again]], but he's still a dick.
** Vaughn was already a narcissistic jerk willing to commit murder. But allowing [[spoiler: ''his own daughter'']] to be eaten by a zombie as he cowered in his office is going beyond the pale.
** Harley as atop the wall between a full on HateSink and a TragicVillain due to his brother's death, but [[spoiler:exploding himself with an entire house full of zombies, including Major's friends and a now human Natalie]] puts him firmly on the asshole villain side.
* {{Narm}}: The cliffhanger ending of "Return of the Dead Guy" is very oddly structured, acting like we have no idea a Romero-ing Liv and Blaine are about to burst in and save Ravi like we saw just a minute ago.
* OneSceneWonder: In "Fifty Shades of Grey Matter", Creator/KristenBell does a DramaticReading for the victim of the week's erotica book, though she only gets a line or two.
* RomanticPlotTumor:
** Season 3 has been criticised for the Ravi/Peyton/Blaine LoveTriangle, thanks to Ravi's depressed attitude in the first few episodes making some [[TookALevelInJerkass find him suddenly unlikeable]], as well as some feeling Reyton being willing to date Blaine simply because he lost his memory makes her look rather naive.
* TheyChangedItNowItSucks: A peeve of some fans of the comic book. Save for the brains and zombie thing, the TV series barely resembles the comics, which were more of a tongue in cheek story that covered a variety of monsters with bits of drama here and there. The show is a straight -faced crime drama featuring just zombies. They don't even use the name of the original character.
* TheyWastedAPerfectlyGoodCharacter: Rita/Gilda, [[spoiler:who is unceremoniously killed by Major when she tries to kill Liv. It was like the writers wanted to get rid of every Max Rager member, even if Rita could have continued to serve as an {{Evil Counterpart}} to Liv if Rita/Gilda joined up with Fillmore Graves.]]
* TheyWastedAPerfectlyGoodPlot:
** The Season 2 winter finale ended with Clive finally getting fed up with Liv's personality swings and cutting off ties with her. This lasts a grand total of one episode, making for flashbacks of Rob Thomas' similar inability to commit to such a big rift between major characters in ''Veronica Mars''.
** In the Season 2 premiere, Liv resolves to not give up on reconciling with her family after they shut her out. This goes completely unacknowledged for the entire rest of the season. Rob Thomas admitted that the season featured so many major ongoing storylines that something had to simply be dropped, especially since they ended up with fewer episodes than they'd planned for.
** After Major becomes a zombie, we only get a single episode of Robert Buckley getting to join in the fun of getting a new personality from eating brains, before he switches to a special blend that doesn't have that effect.
* UnintentionallySympathetic: Liv's voiceover at the end of "Virtual Reality Bites" states that the killer should have just "gotten over" his sister committing suicide after a year of horrific cyber-bullying. Needless to say, many fans felt differently. This may have been what was left of the {{Jerkass}} hacker's brain talking, as Liv is not generally so callous towards the dead or their families.
* WhatAnIdiot:
** Despite knowing that she was a medical examiner for the Seattle PD, one of the suspects in "Brother, Can You Spare a Brain?" actually tried to rape Liv. Made even worse due to the fact that he knew her partner was right upstairs. As you can guess not only did he get his ass kicked by both of them, he was arrested instantly. Of course, he seemed to think she ''wanted'' to have sex with him (thanks to the effect of the brain-of-the-week) and so he probably didn't think it was rape, which sadly crosses into TruthInTelevision.
** Out of everyone in the world, you'd think Max Rager's own scientists would know better than to [[spoiler:mix the drink with Utopium.]]
* TheWoobie:
** Almost everyone who becomes a zombie. They're stuck with a HorrorHunger for brains that will slowly, and permanently, rot their brain if they don't get a fix until they're Romero-style zombies, CantHaveSexEver with anyone other than a zombie to avoid spreading it, have dulled taste senses so they can't enjoy good foods anymore, can't risk getting too excited to avoid an adrenaline rush and go full-on zombie mode, and if they want to avoid the above mentioned Romero-style fate, they only have a few options if they don't want to become a killer: Get a job with access to human bodies (which for many people would be too much Squick to handle), go graverobbing and hope the brains they find haven't decomposed too much (which would be even worse), or hand over small fortunes to Blaine's operation for a fix. And that's without getting into the visions and personality traits they get from the brains' previous owners which can get pretty intense and traumatic. Special mention to Lowell, whose breakdown in "Patriot Brains" sells just how horrible life is for someone stuck as a zombie.
--->'''Lowell:''' (Talking about the brain he just presented Liv) It's Michael Kenny; he was interred yesterday, at Evergreen Memorial.\\
'''Liv:''' You dug up a grave? ...I'm sorry... I'm sure that was awful.\\
'''Lowell:''' It's cake compared to watching the funeral. ...He was a-an English teacher, and all the kids he taught were there, his daughter read his favourite Shakespeare sonnet, and his poor wife was in hell on earth. I-I threw up actually, because, I thought about all the brains I had, and every last one of them, was... we-we eat people. We ''eat'' people.
** Liv in particular. Starting from the traumatic experience the boat party was, which gave her PTSD on top of her zombie-ness, she spent months struggling alone with the problem until Ravi got involved, had to break off from Major at risk of infecting him, her first shot with someone compatible ends with [[spoiler:them being killed when their shared plan to kill Blaine fails, making her blame herself]], the brains she eats often have really negative effects (from making her flirt with a would-be rapist (effects detailed above) to giving her temporary schizophrenia), and the urge to find the person's killer she gets from them leads to her often getting herself and others she cares about in serious danger.
** Major, as a result of his ChronicHeroSyndrome. At first an IronWoobie as a result of Liv breaking things off, Major develops into a full-on Woobie when kids he took care of at a youth centre start going missing, including Jerome (who he cared about a lot), leading to his life to slowly fall apart as he tries to find out what happened. He gets beat up by Blaine's henchmen Julien Dupont when he sees him wearing Jerome's sneakers, and his attempts to prove Julien's involvement leads to him being arrested, fired, losing his new girlfriend, then get attacked and left looking mentally unbalanced to everyone around him, while those who ''do'' know the truth have to let him think he's insane to protect him from what's really happening (and YMMV on whether that's justified).
*** It gets even worse for him in the second season. Vaughn extorts him (via information about the Meat Cute massacre and threats to Liv) into hunting down and killing zombies. His despair over this drives him into Utopium addiction and worse (he fucked ''Rita'', for god's sake).
