* SugarWiki/AwesomeMusic: [[https://www.youtube.com/watch?v=lMsVkRirGk4 "Right Here, Right Now"]] by Music/FatboySlim in "Welcome to Camelot."
* BigLippedAlligatorMoment: The stalker being in unexplained {{Blackface}} when he shoots himself in "Obsession."
* BizarroEpisode: The characters are unknowingly visited by the ghosts of four young people whose lives they failed to save in "After Hours." While there were a few instances of MaybeMagicMaybeMundane, this was the only ''overt'' ParanormalEpisode of what was otherwise a starkly gritty and realistic {{Rescue}}/PoliceProcedural.
* CrossesTheLineTwice:
** After he fails to save a suicidal young man who had changed his mind and decided to live, Bosco just mutters, "... Oops."
** Bosco gets annoyed waiting for Yokas to buy a lottery ticket, so he radios her to yell, "Yokas? Yokas, let's go. Come on. I'm not standing out here all day." When the other customers in the line give her a funny look, Yokas just shrugs and, completely straight-faced, says, "It's a jumper. It's very tragic."
** Bosco trying to handcuff a one-armed man in "Man Enough."
---> '''Yokas:''' You got a foot pursuit. And, uh, he claims to be armed.\\
'''Carlos:''' He's only half right.\\
'''Bosco:''' Stumpy, wait for me!\\
'''Yokas:''' Fighting crime...
* JerkassWoobie: Bosco, beginning in Season 3.
* {{Narm}}:
** The parallels between Joey and a boy who his father, Jimmy, saves from a fire are emphasized by Joey having a [[Anime/TransformersRobotsInDisguise Galvatron]] and the other boy having a Megatron. The title of the episode is even "Transformed."
** The ambulance shooting in "Crime and Punishment" is such a blatant case of ImperialStormtrooperMarksmanshipAcademy that it becomes this, with the gunman opening the back of the ambulance and firing directly into it with a machine gun, only to somehow miss five of the six people who were huddled inside of it (and even then, the one person who he ''did'' manage to hit ended up surviving).
** Carlos's "You touch me again, I'll kick your ass, ''dude''!" from "Spanking the Monkey."
** Donald Mann comes off like a GenreRefugee in the worst possible way, like a Franchise/JamesBond-style baddie decided to slum to fighting beat cops on the streets of Manhattan. The scenes of him hanging out in his mansion, doing things like burning Tarot cards and [[WickedCultured playing the piano]] on a stormy night as we get lots of cuts to a big dragon statue amid lots of DramaticThunder, just feel jarringly dissonant in a show that was once praised as a gritty and down-to-earth {{Rescue}}/PoliceProcedural. He also chucks a man off of a metropolitan rooftop in broad daylight while telling him YouHaveFailedMe.
** The schlubby, middle-aged serial killer from Season 6 baiting his victims into his CreepyStalkerVan with a box full of [[PreciousPuppy Precious Puppies]]. This would be creepy if the victims were little girls, but they were all teenagers and adults, so them falling for such a blatant ruse caused them to come off as TooDumbToLive.
* NightmareFuel:
** The TortureCellar that Lester Martin is revealed to keep his wife (who has gone insane from his abuse) and daughter (who is not even his child, but merely a girl who he stole when she was a baby) in in "In Plain View."
** The hospital shootout in "More Monsters."
** One of the terrorists mindlessly chanting and praying while he literally falls apart and spews blood and bile everywhere due to radiation poisoning in "The Other L Word."
* QuestionableCasting: The show had a lot of random, immersion-breaking, and mostly non-actor guest stars like [[Music/EveRapper Eve]], Creator/RosieODonnell, [[Music/WuTangClan Method Man]], [[Music/{{Kiss}} Gene Simmons]], and Music/{{DMX}}.
* TheScrappy: The gang of {{Vampire Vannabe}} goths in Season 6. While any other show, especially a PoliceProcedural, would probably treat them like a joke, here they were for some reason taken seriously, and even made recurring villains whose arc (which revolved around Yokas's daughter, Emily, herself a largely disliked character due to being a BrattyTeenageDaughter) lasted all of the way into the show's second-to-last episode "End of Tour."
* SeasonalRot: By around mid-Season 5, cracks were definitely beginning to form in the show, as the drama started to get overwrought while the plots became increasingly extravagant, with the season ending with a [[Franchise/JamesBond Bond]]-like drug lord played by [[Music/{{Kiss}} Gene Simmons]] waging war on the NYPD, leading to a DieHardOnAnX scenario when he has his henchmen lay siege to Angel of Mercy Hospital. In Season 6, things just collapsed into melodrama as the characters suffered from one major personal disaster after another while every week it seemed like they were dealing with one high-stakes action or thriller film-like plot after another involving things like a Franchise/HannibalLecter-wannabe serial killer, terrorists building a dirty bomb, a VigilanteMan going after a sexually abusive cult and causing a hostage situation on live TV, a gang of {{Vampire Vannabe}}s going after Yokas's daughter, a dead stalker who left clues to where he had mailed a bomb in a series of videotapes, a conspiracy of corrupt police officers who were the ones who really killed Ty's father, a viral outbreak ([[RecycledScript the show's second]]) and a [[TheChessmaster Chessmaster]] crime lord who was slowly taking over the criminal underworld, culminating in him launching a direct attack on Camelot.
* TearJerker:
** Bobby's death in Season 2.
** When Tommy Doyle's body is brought back to the firehouse in "After Time."
* TheyWastedAPerfectlyGoodCharacter: J.D. Hart, the "rat" police officer turned firefighter who was dropped only one episode after his debut, where he was seemingly set up as a major new character whose presence would cause tensions to flare up between the FDNY and the NYPD.
