* AcceptableTargets: Reporters and people with left-winged political views (however mild) are not exactly given a fair or positive portrayal in this show.
* AlternateCharacterInterpretation:
** Danny, being a major example of the CowboyCop trope, is subject to this a lot within the fandom. The show seems to encourage this, since some of the showrunners worked on ''Series/TheSopranos'', and probably wanted to include at least one morally grey character. Basically, opinion on Danny is divided between those who approve of his policing methods and those who find them excessive:
*** Those who agree with Danny feel that his willingness to break procedural rules is justified given what he goes up against, and at worst view his harsh actions against as merely an example of PayEvilUntoEvil. This is somewhat borne out by these kinds of offenses being committed against the worst people he's dealt with on the show, several of these were out of desperation, and that there are also many examples of him exercising restraint and doing things by the book even when dealing with some really nasty people.
*** Those who disagree with Danny's methods often view him as dangerous, reckless, and view him as having a disturbing disregard for New Yorkers' civil liberties, and many view him as being a KnightTemplar who often comes unnervingly close to becoming as bad as the people he fights. One reviewer pointed out that when Danny decides that a suspect is guilty, he goes after them with reckless and extremely aggressive tactics... but what happens if he ever mistakenly becomes convinced that an innocent person is guilty? Not to mention the dubious legality of some of Danny's methods.
*** Given that Grandpa Henry virtually always (loudly and vigorously) agrees with Danny during debates at the dinner table, opinions on Grandpa Henry have lately also become divided along the exact same lines, with Danny's supporters admiring Henry's opinions, and Danny's detractors disagreeing with them. This is likely intentional, due to Henry being a police officer back when that sort of thing was more common.
*** Around season three or so (and even moreso by Season 5), the show appears to have become much more aware of the UnfortunateImplications caused by Danny's methods (and Henry's support of these methods), and there have now been several episodes where various characters call Danny out for his tactics, and where Danny and Henry (in separate episodes) wind up in hot water for their CowboyCop tendencies/views. Even Frank and other family characters have now given Danny and Henry a WhatTheHellHero speech. Frank has also noted that the decline of methods used back in Henry's time is unquestionably a good thing, because back then officers could and ''did'' rough up people who turned out to be innocent, and that the public nowadays is more trusting and cooperative than it was in the past.
*** This is borne out in the season 4 episode "Secret Arrangements", where Danny is one of several cops being investigated by the D.A.'s office. Frank thinks that while Danny doesn't go ''over'' the line, he steps ''on'' the line, and that his son has always been quick-tempered, impulsive, takes his job personally. Sergeant Gormley tells Frank that Danny is incredibly aggravating and drives him nuts, "but if you've got any others like him at home, please send them my way." At the end of the episode Frank talks to Danny about the newest revisions to the NYPD's interrogation guidelines, detailing recent additions used by their best detectives, as well as methods that would no longer be used or tolerated. Danny snarks about which section he's likely to be in, and Frank responds that he's actually in both. In summary, Danny's an excellent cop and one of the NYPD's best detectives, but he ''needs'' to rein himself in.
** Is Jamie really happy with his status as a patrolman, despite his past disappointment with being stuck while his classmates were already making detective, especially since he proved his mettle by helping to bring down the Blue Templar and infiltrating a crime family and getting one of the key members to testify, all in the first two seasons? Or is he mad at Frank for hampering his way up the career ladder just to avoid any accusations of favoritism so his refusal to take any exam that might give him a promotion is his way of passive aggressively saying "screw you" to his old man?
** Is Frank really the ByTheBookCop he claims to be since his refuses to properly deal with Danny's out of control behavior when ''all'' the evidence points to the contrary and since he absolutely refuses to believe New York City's minority population's grievances against police profiling have any genuine merit?
*** Or does he secretly agree with them but keeps silent to keep the rank-and-file from mutinying against him? Keep in mind that the police union was fully prepared to give him a vote of no confidence in "Family Business" for making a public apology for an officer killing an innocent man in an accident.
** Does Frank or love all his children equally or are Danny and Erin secretly his favorite, while Jamie is TheUnfavorite? Keep in mind that Frank showed Jamie NoSympathy when he was complaining about being investigated by Internal Affairs because of one of Rev. Potter's bogus allegations, while he was considerably more compassionate when Danny found himself in the same situation, even though Danny has found himself in similar situations before because of his hot temper.
* AntiClimaxBoss: Thomas Wilder, Danny's BigBad of Season 6, who has murdered over 20 college-aged women [[spoiler:and kidnapped Nicky[[note]]but he doesn't kill her [[/note]], is killed by Danny in the middle of an open field on their final showdown]].
* {{Anvilicious}}: Not are cops are bad. This is extremely notable because the early seasons often dealt with misbehaving and corrupt officers. But after police related deaths involving racial minorities began to get more public scrutiny in real life, the writers responded by doing more and more stories where officer related deaths are usually justified, charges of corruption are over-blown, and anyone who thinks otherwise is often wrong and trying to carry out an unjustified vendetta against the police -- black characters like Rev. Potter get with this the worse.
* AssPull: Jaime suddenly no longer being bitter over his continually being passed over for promotion and being content with just being a humble officer. It comes out of nowhere and contradicts everything about Jaime before.
* AwesomeMusic: "Theme from ''New York, New York''" as performed by Music/FrankSinatra, plays during the Pilot, introducing the Reagan family as well as Jamie's graduation from the NYPD Academy and Frank's commencement speech.
* BrokenBase: The show's rather flippant attitude towards civil rights is very divisive in the light of the troubling number of controversial deaths surrounding police and African-Americans. It doesn't help that the main civil rights spokesman on the show, Rev. Potter, is corrupt and usually has to resort to cliche straw arguments and fabricating confrontations in order to continue his war on the NYPD, or that the show seems to support real life controversial methods like "Stop and Frisk" (which InUniverse Frank only agreed to stop supporting ''after'' Jamie pointed out that many cops were using it as a crutch), or an having entire episode dealing with the "Blue Wall of Silence" while still having all InUniverse critics of the police be obnoxious strawmen of whom Potter is the most recurring.
* CompleteMonster:
** [[SmugSnake Richard Reed]], from season 1's "Re-Do", a vicious SerialKiller and [[SerialRapist rapist]] of women, is a [[HeManWomanHater misogynistic]] sadist who thinks all women are his to use and abuse. He later has his conviction overturned because a lab tech screwed up the protocols. With help from his fan club, he terrorized his surviving victim into silence and decided to let one of his fanboys have her. Even his own kin are not safe as Richard beats his sister and ties her up for saying something she "shouldn't have." Later he [[SlashedThroat slits a janitor's throat]] and attempts to perform his usual MO on Erin Reagan, the ADA who convicted him, before she is saved by Frank. Void of any redeeming qualities or mitigating factors, he stands as one of the very worst the Reagan family went against.
** [[RedBaron The Phantom]], real name [[GangBangers Donald Washington]], from season 2's "The Life We Chose", is a cold-blooded crack dealer and murderer. In the beginning of the episode he ruthlessly shoots detective Cruz and kills Detective Gates, who pleads that he has three kids and to which the Phantom replies "Too bad for them". This shocks even his own cohort who was only planning on robbing them. [[YouHaveOutlivedYourUsefulness The Phantom would later kill his cohort when he didn't need him anymore]]. He later goes after other members of Task Force Apache, the police sting that sold him out planning on killing all of them to keep his drug dealing business running smoothly. Greedy and wishing to make his vile business run smoothly, he cares for no one but himself and is an utter psychopath.
** [[TheMafiya Uri Denko]], from season 2's "Working Girls", is a ruthless ArmsDealer who Erin is prosecuting, and a cold-blooded sadist who executed a man's wife in front of him in their living room over a business dispute. He later threatened the man's children in a courtroom outburst to scare him into not testifying but still has him killed anyway after the threats scare him into running. He then puts out a hit on the surviving witness and hounds her mercilessly, and sends men after her grandmother back in Russia as well (fortunately the FSB got there first). A sociopath of the highest order, he would step on anyone who gets in his way.
** [[FauxAffablyEvil Santana]], from season 3's final two episodes "The Bitter End" and "This Way Out", is [[GangBangers the leader of the Los Lordes gang]]. He and his gang are responsible for turning the Bitterman projects into a hellhole and hounding the residents, making them scared for their lives to the point that one young mother [[DrivenToSuicide commits suicide]] with her son to get away from him. After her death and Detective Danny Reagan's attempts to take them down, he declares war on the police department and [[CopKiller arranges for ambushes]], one of which kills Jamie's partner and friend Vinny. He later takes advantage of a mentally-impaired man by tricking him into shooting Mayor Poole by having him think it would be a harmless prank (leaving Poole a paraplegic). After his girlfriend is arrested with his drugs, he panics and puts out a failed hit on her in prison. Santana shows that under his calm and collected demeanor is someone who cares only about himself and would step on anyone who gets in his way.
%%Do NOT add CompleteMonster entries without going to the cleanup thread first.
* CreatorsPet: Frank. He's always right about everything, no matter what the circumstance and never seems particularly interested in listening to people who have differing opinions about more controversial police policy, and the writers do everything in their power to make those people -- particularly Mayor Poole and Rev. Potter -- always in the wrong no matter what.
** Of course he's the creator's pet. He's portrayed by Tom Selleck, the star.
* CriticalResearchFailure: At the beginning of "Hall of Mirrors", there is a cricket game being played in Central Park with remarkable accuracy, except that there aren't any wickets. It's funny as hell.
* FamilyUnfriendlyAesop:
** Season 7 gives us the wicked notion along the lines of, don't be a hero, because some people are too cynical to appreciate it, and some people don't want to be helped, and will hate you [[StopHelpingMe for helping them when they didn't ask for it]] (when one should encounter selfish people who gripe, "[[ItsAllAboutMe You don't know what's best for me, but I do]]"), while the very definition of doing good ''is'' selfless acts of assisting others even when they don't ask for help. Nicky attempts to help a [[DirtyCoward rat of a woman]] who is under the thumb of an abusive husband along with her son. Sure, she wants to do the right thing, but this hag is completely ungrateful. Not only does this woman shit on Nicky at every turn, she screams hatred toward her after Nicky's actions inspire her son to stand up for himself and stab his abusive father, causing a police incident that will wrench their family apart and basically wants her to drop dead for doing what she did and had her in tears. Someone go find that witch and shove her broom up her ass!
** The Season 7 finale, where Danny's actions usurp the chain of authority, mess with an FBI operation, and get his household burnt out. This one is as plain as day: sometimes, people get blinded with the idea of doing the most good possible and will not settle for anything less, even if it means others will suffer in the process of obtaining swifter justice, when doing just a little good would have sufficed and led to the greater good in the long run, without all the hassle of innocents getting hurt. Or, put more simply: impatience kills.
* HarsherInHindsight:
** The Season 3 episode where Frank has to deal with a bigoted right-wing talk show host doing a show in the city. Mayor Poole and Rev. Potter want to cancel the show via LoopholeAbuse, but Frank allows the show to happen ... making sure that the security detail is assembled of African-American and Latino officers just to piss the host off. Beginning in 2016, more and more white supremacists feel emboldened to spread their hate -- culminating in a 2017 rally in Charlottesville, VA where one bigot ran his car into a crowd of peaceful activists protesting a white supremacy march.
** One season 4 episode has the NYPD being subject to controversy after an officer is alleged to have shot an unarmed teenage boy[[note]]the boy ran away while two of his pals were firing potshots at Jamie and Edie; as it turns out the boy was armed with a gun and a bystander picked it up[[/note]]. It aired ten months before the shooting of Michael Brown in Ferguson, Missouri under similar circumstances.
** Another season 4 episode involves a death in police custody caused by an officer using an illegal chokehold; the DA refuses to press charges against the officer (though Frank fires him). This was about a year before Eric Garner died.
** Every single Linda scene, [[spoiler: given her fate]].
* InternetBackdraft: [[spoiler: Linda being killed via BusCrash between Seasons 7 and 8. Her death serves no purpose other than to give Danny angst, not to mention she was one of the most kind-hearted and level-headed characters on the show. The one saving grace about it is she died in a hospital helicopter accident instead of [[StuffedIntoTheFridge being killed by criminals looking to get back at Danny]].]]
* LikeYouWouldReallyDoIt:
** Frank is shot at the beginning of "Dedication" in a drive by. He lives.
** Via creative editing and judicious use of a {{Stock Sound Effect|s}}, [[NeverTrustATrailer the trailers for the season 3 premiere]] made a valiant effort to convince us that the Criminal of the Week would blow up Danny and Jackie. He didn't.
** The Season 8 trailers have the new Mayor firing Frank. It ''does'' happen, but it turns out since she's only the ''Acting'' Mayor she can't actually fire him so it's an empty threat.
* {{Narm}}: Some of Reverend Potter's facial expressions during his more-heated tirades can look downright cartoony.
* NightmareFuel:
** The girl who kills herself and her baby to avoid a FateWorseThanDeath by the BigBad gang in "The Bitter End." And yes, you even get to see the dead bodies afterward. (*Shudder.*)
** Nicky getting kidnapped by a serial killer ImpersonatingAnOfficer; what makes this creepier is that Nicky had every reason in the world to trust a cop, even one she didn't know personally. She's their boss's granddaughter after all.
*** Not to mention that this is a story arc that's been going on for the whole season. We (and Danny) know what kind of depravity this guy is capable of and are just as terrified as her family at the thought that Nicky is going through that.
* ReplacementScrappy: The New Mayor in Season 8, who's just the latest in a long line of left-leaning city officials whose sole narrative purpose is to disagree with certain police policies and be proven wrong by Frank, and she's more abrasive than Mayor Poole was; she's just a another liberal strawman offering nothing new to the narrative.
* RetroactiveRecognition:
** [[{{Series/Daredevil2015}} James Wesley]] is the SerialKiller in "Re-Do".
** [[{{Series/Nashville}} Luke Wheeler]] is the ex-cop turned would-be bank robber in "Critical Condition".
** [[{{Series/Blindspot}} Tasha Zapata]] is a rape victim that Erin convinces to testify in "Protest Too Much".
* StrangledByTheRedString: A rare positive example with Jamie and Edie, who ''get engaged'' after a NearDeathExperience finally makes them acknowledge their feelings for each other, opting to skip over all that pesky dating. Which actually makes sense, as they've been friends and partners for years and don't really need to date, as they already know everything about each other.
* StrawmanHasAPoint: Reverend Potter ''is'' an AttentionWhore who ''does'' take any opportunity to manufacture confrontations with the NYPD and Frank's family, but he's right on two counts: Danny ''is'' quick to resort to force and often goes too far (though somehow Potter has never caught him at a ''legitimate'' case of PoliceBrutality), and the existence of the Black Lives Matter movement in real life meant to demonstration the discrimination of police against non-whites.
* UnfortunateImplications: [[http://www.slate.com/articles/arts/culturebox/2014/12/blue_bloods_starring_tom_selleck_the_nypd_white_viewers_and_black_new_yorkers.html This]] review critique of the show points out how the show reinforces negative stereotypes about racial minorities by often having them portrayed as untrustworthy by having them manufacture fraudulent claims about police brutality.
* UnintentionallySympathetic: The writers never want us to sympathize with critics of the police, but given the NYPD's obstinate attitude to any charge of misconduct and there refusal to properly address their concerns, and Danny's wild conduct, the opposite often occurs.
* UnintentionallyUnsympathetic:
** Danny Reagan whenever he is framed for performing corrupt actions. While the audience is supposed to feel sympathy for him given he's a good cop being railroaded by someone else, it's hard given the fact that Danny ''has'' committed DirtyCop actions (i.e., waterboarding, putting a gun to the back of an unarmed suspect, threatening to pull a suspect's medical tube, etc.), but has yet to face his comeuppance. His sympathy points are lost furthered given his statements on how people should be held accountable for their actions, but that doesn't apply to him.
** Sarah Grant in "Bad Company." Giving her family's killer NoSympathy is quite understandable... initially. But bitterly and coldly continuing to do so even after knowing that he didn't intentionally do it (he was an untreated schizophrenic at the time) and is now lucid enough to try to be TheAtoner, is another thing entirely. And the icing on the cake is when she ultimately tells him that the only true way to make up for it is to commit suicide (despite her knowing that he already attempted just that in the past). Needless to say, it's pretty hard to watch her look so happy and unfazed at her wedding afterward, without one feeling bitter after all of that.
** Frank in the Season 8 premiere. An off-duty officer shot an ''unarmed'' suspect (though high on drugs and had a criminal record) for attempted shop-lifting; Frank and his circle (sans Garrett) consider it a justifiable shooting, the new Acting Mayor (formerly the Public Advocate) does not, and she tries to fire him over his rather blasé response to it -- the victim was a criminal so she deserved to die in lieu of a being put on a trial; as acting mayor she does ''not'' have the authority to so, per the city charter.
* TheWoobie:
** Officer Jamie Reagan -- He has been put through ''a lot'': His fiance left him, he was tricked into a SuicideByCop, he watched his first partner Vinny bleed to death, and he has strong feelings for his second partner Eddie, but they are forced to pretend they don't have them otherwise they'll be assigned new partners. There's also the fact that many cops think he's an EntitledBastard because his father is the PC, something that is ''not'' true, but because of the relation, he has yet to be promoted to detective (despite being qualified), and thus has [[TookALevelInJerkass taken a level in jerkass.]] Then after he decides that his brand of cop is necessary exactly where he is, he gets told by several people that he needs to be more like [[CowboyCop his brother]].
** Detective Alex Fuentes from "Burning Bridges" -- He is a good cop who was outed as a gay man after stopping an attack outside of gay bar. As a result his homophobic partner (who Fuenets has been friends with and has even been there when his partner went through marriage troubles) wants a new partner (which Gormley does). And while with Baez, Fuentes informs her that his own family has disowned him. Things gets better with his partner but still...
** Ernie "Goodnight" Mason from "Not Fade Away" -- Ernie has spent the last 12 years in for a crime he didn't commit. After being released, he learns his ex-wife is with the man who set him up. His son, who is in boxing, doesn't want anything to do with him. He is nearly shot, which convinces him to leave New York since he has no one left. And when he changes his mind to get the real killer, he is ''killed''. The day after his son won his first match and when said son was looking like he wanted to spend more time with his father.
