* AlternateCharacterInterpretation: Every character (particularly the older ones) is looked at as this (i.e., Munch, funny DeadpanSnarker or emotionally damaged [[TheCynic cynic]], Bayliss, sympathetic [[TheWoobie woobie]] or weak StrawLoser, Pembleton, witty, hard-working [[TheHero hero]] or [[BlackAndWhiteMorality Black-and-White thinking]] snob?) But a vocal community has subjected Lewis to this trope. Cool, [[FairCop handsome]], and the most stable of all the cops, or an aloof, cocky JerkAss who [[ItsAllAboutMe only looks out for number one]] and seems to make [[NiceJobBreakingItHero a variety of serious errors?]]
* ArcFatigue: The aftermath of the Luther Mahoney shooting in Season 6 started with a newcomer (Falsone) having a burning interest in a police shooting of a drug dealer from the year prior, morphed into laughable dramatics from Mahoney's "long lost sister," and basically destroyed Lewis, Kellerman, and Stiver, three regular characters well liked by the fanbase. Made worse by the fact that the shooting wasn't a black and white issue.
** Sheppard's gun-taking fiasco from season seven, which made her look weak, incompetent and untrustworthy. Lewis, regardless if he were justified in doing so or not, looked like an even bigger JerkAss who alienated the others against her and even the [[CreatorsPet "go]][[DesignatedHero od"]] female detectives turned on her for making ''them'' look bad. Even worse, this ended up being one of the seasons' ''main storylines.''
* SugarWiki.AwesomeMusic: Many examples. The soundtrack fits in the likes of Music/NineInchNails, Collective Soul, Music/ToriAmos, Suzanne Vega and Music/JimiHendrix and it is awesome.
* CompleteMonster: Due to its morally ambiguous nature and realistic tendencies, the show didn't have many of these, preferring to keep their villains as pathetic figures. But a few do stand out. The most prominent is Luther Mahoney, a Drug kingpin who has complete control over the Heroin deals in Baltimore. He escapes justice time and again and just loves rubbing his wealth and KarmaHoudini status in the face of the Detectives. He's also very smart, making himself a [[VillainWithGoodPublicity pillar of his community]] that no one wants to think anything bad about. His crimes include murdering rival dealers and anyone who stands in his way, intimidating witnesses, and ordering murders. He had children killed over a few hundred dollars and ordered a local corner store owner murdered simply because he chased away the dealers who would sell outside his store. It's mentioned at one point that he is responsible for dozens of murders.
** His nephew Junior Bunk also qualifies. In the course of a few episodes, he murders witnesses, kills a judge and shoots up the Homicide unit (Killing three officers and wounding two detectives) with a joyful smile on his face.
* CreatorsPet -- Falsone, who solved all of his cases (including one cold case), made up with his wife, and simultaneously successfully investigated every single aspect of Kellerman's Mahoney shooting without attracting any criticism outside of Kellerman. He was brought closer to Earth in Season 7.
** Arguably Ballard was a far worse offender, at least initially. The episode in which she first appeared had Giardello and all the members of the unit who didn't get transferred [[CharacterShilling talking about how great a detective she was]]. The same three-parter had her moaning about how [[ChillyReception Pembleton doesn't seem to respect her]] and has Pembleton refuse to follow a completely obvious lead (instead following one that was completely out there) just so that she could look good. Fortunately she became increasingly side-lined (unfortunately in favour of Falsone). Unfortunately she never went away.
** Most of Season 6's additions probably also count, with fan-favourites Pembleton, Kellerman and Lewis getting sidelined in favour of storylines involving the newer characters. The TV-movie saw some of these characters get relegated for old favourites.
* EnsembleDarkhorse: Munch has retro-actively become this.
** Pembleton was, and continues to be, Homicide's most popular character. To the point that the only season without him is what killed the series.
* GaryStu -- Falsone, especially in the sixth season.
* HarsherInHindsight -- In "A Many Splendored Thing" Adrienne Shelly plays the friend of a murder victim who thanks Bayliss and says she is happy to know that if she is murdered, Bayliss will avenge her. In 2006, she was murdered in a robbery of her NYC office.
* HoYay -- Bayliss and Pembleton.
** To further complicate matters, in the series finale Bayliss admits that he 'loved' Frank but it's unclear in what sense i.e. romantically or like a brother.
** Let us not forget Munch and his whole obsession with Stan "The Big Man" coming back ''for an entire season.''
* IdiotBall:
** The first episode of season six features a murder committed by a member of a reputable black family. They give the idiot ball to Pembleton, who refuses to even consider that a member of this family would perpetrate this crime because they were black, friends of Gee, and did a lot of good for the city, even though their only other lead was such a long shot and Pembleton is, unlike Bayliss, usually free of such hang-ups. The reason they gave Pembleton the idiot ball was so [[CreatorsPet Ballard could look good]]. Understandably this probably pissed off a lot of fans who hated Ballard, and there were quite a few.
*** Creator/AndreBraugher, who played Pembleton, was also probably very irked about it as well, as after the season ended, [[ScrewThisImOuttaHere he wound up leaving the show]]. To be fair, the network had already scuttled the Pembleton stroke arc (which Braugher liked because he wanted to depict a Pembleton who had to face more challenge and difficulty in his work) and now he had to contend with being side-lined in favour of the network insisted super-model cop.
* JerkassWoobie: Munch. An insufferable, sarcastic jerk he may be at times but so many bad things have happened to the guy (Being dumped by various women, being bullied in school, being clearly traumatized after seeing his friends shot, and feeling guilty over his abusive father's suicide) that You can't help but feel bad for him.
** Pembleton could be a complete jerk but only a person with heart of stone couldn't feel sorry for him after his stroke. Pembleton's best resource was his mind, so his loss of cognitive function is tragic, added to which his wife just had a baby, making his inability to go and work as well as his need to be cared for by her even more tragic.
** Felton, again a complete prick but given the way his crazy wife treated him you couldn't help feel sorry for him when he started drinking, turning up to work late (or not at all) and losing key pieces of evidence. And while you kind of agreed (Felton was nowhere near the best detective), Gee telling him that he wasn't good enough for the unit after he'd been shot must've hurt.
** Bolander could be a cantankerous old man, especially in the way that he treated Munch. But you felt sorry for the way his wife left him, especially since they obviously still loved each and especially since Bolander finds it so difficult to try and rebuild his life outside of work after losing her.
** Kellerman. His wife cheated on him. His partner (and supposed friend) won't open up to him. He's accused of taking bribes even though he didn't. He has a somewhat abortive relationship with Julianna Cox which basically ends because he's such a mess he can't explicate his feelings for her. He kills a bastard drug dealer pretty much in defence of his supposed partner/friend (how was it going to look if Mahoney revealed Lewis beat him up? Plus, he lowered his gun but he didn't drop it) and what does Lewis do in response? Turn his back on him. He eventually gets kicked off of the Police force for killing a total bastard, and everyone he worked with thinks he's trash.
* MoralEventHorizon -- An interesting example of this trope involves Kellerman. His point of no return does not seem to be the execution of Luther Mahoney, but rather a smaller, quieter scene in which he laughs at a young dead drug dealer on a crime scene, arriving as far as posing for a mock picture next to his corpse. From that point on, the writers portrayed him as increasingly bitter and unlikable - no longer an AntiHero, but simply a JerkAss.
-->'''Det Ballard''': We speak for the dead, remember?\\
'''Det Kellerman''': Screw the dead. What have their moldering asses ever done for me?
** The latter scene was facilitated by the former, which was such a moral event horizon that Kellerman, who previously quit, started smoking again and descended into bitterness. He somewhat redeemed himself during his guest appearance in season 7, however.
* {{Narm}}: The scene between Lewis and Kellerman on the latter's houseboat in the "Have a Conscience" episode. Aside from failing to portray [[UnintentionallyUnsympathetic Kellerman as sympathetic]] and [[NoSympathy Lewis as genuinely concerned]], it just looked like a poorly done version of the [[spoiler:suicide scene]] from ''ScentOfAWoman''. Also, what was the point of Lewis' comment of him trying to stop it so that [[WhamLine "no one else blames me again for my partner's suicide"?]] It made him look like a conceited [[JerkAss jerkass]] who did it not out of concern for his partner, but for reasons involving [[ItsAllAboutMe self-preservation and narcissism.]]
* NightmareFuel -- The episode "Subway." A man ([[Series/LawAndOrderCriminalIntent Vincent D'Onofrio]]) is shoved on a subway platform and is pinched at the waist between the platform and a subway train. We spend the rest of the episode with him as he's waiting around to die. He is lucid the entire time.
** Pembleton in the season four finale "Work Related". Aside from showcasing how excellent an actor Andre Braugher is, it is just so damn haunting, from the very realistic moment of his stroke happening to at the end of the episode, where we see the poor guy desperately screaming and pleading for help...''while trapped inside of a coffin.'' This is made even scarier over the fact that, at the time, fans didn't know if he survived his ordeal.
* PoorMansSubstitute: The writers seemingly wanted to set-up Gharty as Bolander's poor man's substitute. This is lampshaded by Munch, who claims that a certain trait of Gharty's reminds him of Bolander. However, this [[AnalogyBackfire analogy falls down]] in a number of places. For example, while broadly they might be similar (Both are older, in less than perfect shape and fairly conservative Gharty has a number of negative personality traits not shared by Bolander that ultimately make him less likeable (Gharty is a bigot, a coward and usually flirts with Munch's bartender/girlfriend/fiancée/wife). In addition Gharty lets himself get pushed around in ways that Bolander would never stand for.
* ReplacementScrappy -- Ballard, Sheppard, the younger Giardello, Falsone. Any character introduced after S5.
** Season 7's line-up is this particularly because of Pembleton's departure. While Giardello Jr is a decent character (albeit underdeveloped), he is no replacement for Frank Pembleton.
** Kellerman at least partially qualifies, being a younger, more attractive replacement for three older, fatter detectives. But unlike previously named examples, Kellerman fit perfectly into the cast and rhythm of the series.
* RetroactiveRecognition -- Jeffrey Donovan of ''Series/BurnNotice'' appears as a redneck spree killer. [[spoiler:And his mild-mannered twin brother!]]
* SeasonalRot: There's a lot of debate about this and really any point after the third season is up for consideration.
* TheScrappy -- Falsone was so loathed by some fans that one of the first television hatedom websites was created in his honour.
** Ballard.
** The fact that Sheppard was almost universally referred to by fans as "Sheepdog" shows that she qualifies for this too -- without being competent enough to be a CreatorsPet.
* TheyWastedAPerfectlyGoodPlot: Bayliss' character switch towards the end of season five when he ended his partnership with Pembleton and became an IronWoobie and a {{Determinator}} and stopped allowing the other detectives, especially his former partner, to walk all over him. The writers, [[WhatAnIdiot for some reason]] [[TheyJustDidntCare or another,]] didn't like this and turned him back into the regular [[TheWoobie woobie]] that the audiences saw earlier.
** Ned Beatty's leaving meant they couldn't do more with his adjusting to being back at work after being shot. The best they could do was imply that it changed him, as Bolander would never have previously done what he did to get himself suspended.
* TheWoobie -- Bayliss.
