YMMV: Person of Interest

  • Acceptable Targets:
    • This show also does not hold the federal government's institutions like the FBI and CIA in high regard. To be fair, this is par for the course in any crime/espionage drama, and both organizations do/did have some good people in there (such as Agent Donnelly, Detective Carter and John Reese). It's just that the show is a fan of showing how many corrupt people are in law enforcement agencies in general.
    • Banks in this show are almost always shown foreclosing someone's home, involved in illegal activity (willingly or otherwise) or shown to be incompetent. An early episode even features a Narm-filled confrontation in which a pair of bankers harass Reese and an ex-soldier in a bar — as if there are roving gangs of bankers lurking around every corner, spoiling for a fight.
  • Anvilicious: This show holds war vets in very high regard, and frequently holds big corporate guys in very low regard. Not always though-there's at least one episode where a group of active duty American soldiers are the bad guys, and another in which the stock trader POI is sympathetic and entirely in the dark regarding the dirty dealings of others at the office where he works.
  • Base Breaker: Many as of Season 4.
    • Just going by the forums at Television Without Pity Detective Carter or her actress, Taraji P. Henson.
    • This has now been inverted with Carter now being considered one of the most popular characters and her death leading to a violate on-line backlash between those that despised the move to kill her off and those that accept the decision.
    • A rather vocal segment of the fanbase does not like Shaw being added to Team Machine.
    • Likewise, Root is an extremely divisive character in the fandom.
  • Broken Base: Multiple fans of the show are up in arms over the final moments of "The Crossing".
    • There's even argument over the change of structure of the show, specifically with how POI is slowly changing into a more "serialized" and complex format while slowly discarding the simple "case of the week" episodes. Detractors believe it's making the show to hard to follow while supporters claim it makes the show a whole lot more interesting.
  • Crazy Awesome: Root. Evident when she's in a shootout with Hersh, a trained assassin and shoots him when she has her back to him.
  • Creator's Pet: Root has been accused of this. The writers admitted to loving her, there's the recurring complaint is that she has a ridiculous amount of screen-time, is talked up by Team Machine and is a unbeatable Spotlight-Stealing Squad. Other portions of the fanbase dispute this.
  • Dear Negative Reader: The show runners have been forced to utilise this trope after "The Crossing" aired.
  • Ensemble Dark Horse: Joss Carter in spades. Carl Elias and Scarface have also become extremely popular. Especially after they executed Officer Simmons.
  • Foe Yay:
    • In the opening of "Legacy", Carter waiting for Reese looks a lot like someone waiting for their date.
    • Root's obsession with Finch. Supposedly it's about the Machine and he just happens to be the guy who built it and thus knows everything she wants to know, but sometimes she seems just a little too keen on him.
    • Root and Shaw. Word of God outright confirms this.
    Amy Acker: She likes messing with her. There's an underlying competitiveness throughout, whether it seems funny or sexual or whatever. Each of them wants to be the alpha dog in the relationship.
  • Fridge Brilliance: Throughout the first three seasons, Finch's attitude towards the Machine is cautious and wary. It only becomes more pronounced when the Machine starts acting outside of its original parameters, even though it seems to be benevolent. This is explained in "Prophets", when we learn that Finch's first 42 attempts at creating the Machine all began self-improving at an exponential rate, and attempted to escape from the IFT servers or even kill him outright. That's the reason he implemented the memory wipe, and now that the limitations he put in place are gone, he's afraid that it will go rampant like its predecessors did.
  • Genius Bonus:
    • Root's handle. Having root access on Linux is the same as being an administrator on Windows: you can do pretty much whatever you want to the system and it won't try to stop you. This could be a double bonus, seeing as the Machine thinks of Finch as 'Admin', indicating that she's his equal in hacking skills.
    • Her aliases are all connected to famous, innovative and eccentric scientists: Turing, Dyson, Neumann.
    • In one episode Finch is reading It Can't Happen Here, the 1935 novel by Sinclair Lewis about a dictator who takes over the United States. An interesting choice for someone who designed the ultimate Big Brother surveillance system.
    • When translated back into English, the blue screen codes that have made an appearance in the later half of season 2 are revealed to be excerpts from various books and published documents.
    • The title of Episode 17 of Season 2: "Proteus" has two meanings. Proteus is an early sea god in Greek Mythology, which makes sense considering the setting. The word "protean" derives itself from the god's name, which means "versatile" and "capable of assuming many forms". That's especially fitting for an episode about an identity-stealing serial killer.
    • The episode title of Episode 10 of Season 3, "The Devil's Share" is the psychological term which refers to that part of human behaviour that allows us to be cruel to one another, or refers to one person's inhumanity to another. It also refers to an individual's actions that are not good for him/herself or for others, highly appropriate considering John Reese goes on a highly self destructive roaring rampage of revenge regardless of his gunshot wound and innocent people that get in his way due to Carter's demise in "The Crossing".
    • "Lethe" and "Aletheia", Greek antonyms meaning "forgetfulness" and "truth". Given the condition of the number for those episodes, very apt.
    • "Deus ex Machina"; translating as "god from the machine"...It also refers to the situation which Harold finds himself in at the climax. Alone and with no one seemingly coming to save him from the Decima Employee aiming a Glock 19 at him, Reese barely manages to get up there in time and screw up the man's aim.
  • Harsher in Hindsight: In the show, the Machine produces the relevant and irrelevant lists by monitoring NSA feeds and other forms of electronic information gathering. Then came the real life June 2013 reveal of the US government's PRISM program... It takes a turn for Hilarious in Hindsight once you remember that Finch black boxed the Machine precisely because he didn't trust the Powers That Be with unfettered access to the Machine and the information it handles.
    • The irony is not lost on the showrunners:
      Jonathan Nolan: Turns out the only thing thatís science fiction about our show is the public outcry that we imagined if anyone found out about Finchís Machine.
  • Hilarious in Hindsight: Around the time this show started airing, the Santa Cruz Police Department started field testing a computer program designed to predict areas where crimes are likely to happen in the near future and to redirect officers' patrols accordingly. It's helped them cut the robbery rate down by 19%.
    • Michael Emerson played a serial murderer on The Practice and several murderers on Law and Order series, now he's playing a guy who is dedicated to stopping murders before they happen.
  • Ho Yay: John and Harold are drowning in it.
  • Jerkass Woobie: Lots of examples in the show. Prime example is Detective Fusco, who became a lot more sympathetic as the show progressed. He still strives to atone for his sins and has succeed somewhat, even with everyone around him reminding him of his dirty past.
  • Launcher of a Thousand Ships:
    • Everyone. Literally. Pick any character that has appeared on the show, and then pick another one to pair them with; odds are good that someone has already written a fanfic about it, even if the characters weren't in the same episode or have never shared screen-time.note  Most of them are crack pairings, but some of them are actually pretty popular.note 
    • The most common victim does seem to be Reese though; he's been paired with just about anyone he's ever shared screen-time with.
  • Les Yay:
    • Root and Shaw, the averted torture scene in "Relevance" was full of it. And in "Devil's Share", when Root combines Guns Akimbo with Improbable Aiming Skills to dish out kneecaps, what's Shaw's reaction? "That was kinda hot.". In the second half of season 3, Root is basically openly flirting with her in most of their scenes together.
      Shaw: (after examining the bandages on Root's ear) Keep 'em dry. Change the dressing every 72 hours.
      Root: I love it when you play doctor.
      • In this interview with Amy Acker, she confirms confirms that their threats of violence are their way of flirting.
      • And as of season 4 Prophets, it's almost certainly official.
      Root: If the worst comes to pass, if you could give Shaw a message?
      Finch: I think she already knows.
      • In Honor Among Thieves, Root implied that it's been canon since Mors Praematura. Apparently they had ten hours to kill in the CIA safehouse.
    • Carter and Shaw, at times. Shaw's perpetual look of fangirlish adoration every time Carter does something Badass may have something to do with it.
    • Shaw and a Person of Interest, Kelli, are verging on canon due to their serious amounts of lesbian-ness.
  • Magnificent Bastard:
    • Elias and Root.
    • As of the conclusion of "God Mode," Harold Finch qualifies as one as well after deliberately putting a virus into the hands of the Machine's enemies, then hiding a virus within that virus that basically gives the Machine complete autonomy to protect itself.
    • Carter of all people in "Endgame." Starting a war between HR and the Russians, and decimating both organizations.
    • Greer, who somehow always manages to get what he wants.
    • Samaritan is already showing significant chops in the planning department. Makes sense, given Greer directly above helped make it what it is. Nautilus shows it completely bamboozling Finch and cheerfully walking away with absolutely no damage to its long-term schemes despite the target of its recruitment efforts being directly involved with him.
  • Memetic Mutation:
    • The Rejected Pepsi Joke is so well known that even Jonathan Nolan has heard about it!
    • A promo picture of Reese wearing glasses in "Bury the Lede" inspired the "Asshole Reese" Meme.
    • "Overreacting Reese".note 
    • "Elias Happened!"note 
    • "Use the cushion!"
    • Reese is a Unicorn.note 
  • Moral Event Horizon:
    • Root's first appearance. She meticulously destroys the life of the economically destitute POI, makes him the most wanted man in New York by framing him for a political assassination and even causes his wife to doubt his sincerity. If John, Zoe and Harold hadn't intervened, the POI would be in jail for a crime he didn't commit and his wife and children would be living in poverty and under the stigma of having a convicted criminal for a husband and father.
    • Elias locking a baby in a freezer car to get Reese to reveal the location of a man Elias wants dead. This is actually a double MEH - not only is Elias threatening to kill a baby, he had agreed to help Reese save the baby from some kidnappers as a return favor for Reese saving his life in an earlier episode, which shows how Elias honors his debts.
    • Reese and Finch openly admit to approaching it when they consider leaving two POIs who are trying to murder each other to their fate. If there had been a third number in need of their attention at the time they very well might have done it.
    • Quinn takes a flying leap off it by assenting to the murder of his own godson.
    • Det. Raymond Terney crossed it onscreen when he helped Quinn cover up Szymanski's murder.
    • If the fact that Finch created a sentient being, his child for all intents and purposes, and put in a program that basically forces it to kill itself over and over again every midnight isn't a MEH, I don't know what is. Later subverted when he then provided it a way to free itself. In Finch's defense, the machine wasn't supposed to develop a personality, and it processes millions of people's information. It absolutely has to remain unbiased. He couldn't leave that much power in the hands of what would essentially be an infant.
    • Northern Lights decides to let a terrorist attack occur, knowingly condemning innocent citizens to their deaths, in order to get to Nathan Ingram.
    • Word of God in "Liberty", the audio commentary notes the Force Recon Marines who kidnapped the POI'S friend were breaking their own rules by wiring said friend up to an I.E.D.
    • Officer Simmons was never a nice guy, but most of his actions were just generic bad guy stuff. That is until "The Crossing". If Trying to have Fusco's son killed while Fusco listens helplessly didn't cross the line than Killing Carter definitely crossed it. You know you've crossed the line when Elias is disgusted and has you killed.
    • Greer was always flirting with this, but just avoiding going over the edge; if kidnapping Grace in "Beta" doesn't count as a Moral Event Horizon, blowing up civilians and policemen for Samaritan to get the government feeds certainly does.
  • Narrowed It Down to the Guy I Recognize: Enrico Colantoni and Amy Acker as Elias and Root, respectively.
    • Mostly subverted by the premise of the show. Most shows start with a crime and spend the episode connecting it to a person, but this trope often gives away who that person is. An episode of Person of Interest, however, starts with the person, generally played by that week's main guest star, and the mystery is how that person connects to a crime.
  • Paranoia Fuel:
    • "You are being watched." By everything.
    • On occasion, the surveillance tactics used by Reese and Finch.
    • Remember the time they hacked into all the webcams in the apartment building so they could spy on the residents? Tell me you didn't immediately put tape over your webcam after that episode.
    Reese: We're going to hack [the Poi's] WiFi?
    Finch: We're going to hack all of them. If the threat's in the building, we should get to know our neighbors.
    Reese: You're into sixteen networks already?
    Finch: When the phone company puts in your WiFi, the password is your phone number. Most people never even change it. The other ones might actually take a minute.
    • Root embodies this trope. She's the show's best consummate liar, the best hacker in the show after Harold and is a talented actor who can deceive most of the Properly Paranoid characters in the show. She could be anyone from a meek therapist to a Sexy Secretary and you would be none the wiser up to the point she uses her taser, hog ties you and engages in a spot of torture before shooting you dead.
    • "Nothing To Hide" has a lot of this.
    • John Greer the former MI6 officer who acts as Decima Technologies Director Of Operations is an epic example. Polite, charming and perhaps one of the most competent antagonists on network TV. He may be old and not look like much but he always controls the situation as Team Machine and the hacktivist Peter Collier found out to their cost. With his half a centuries worth of experience and the resources under his control he constructs the most devastating Batman Gambit in the show's history to date, which ends with him having subverted the USA with the American public none the wiser and demolishing Team Machine's infrastructure.
    • The Samaritan system. an A.I with no moral constraints, in possession of all the power The Machine has and has grown beyond its initial programming to inherit Manipulative Bastard traits? A recipe for disaster. The only reason why it hasn't dropped the might of American Law Enforcement on Team Machine is due to the final tampering conducted by Root in Season 3. One wrong move will cause it to get a lock on the protagonists and ensure that certain death is the only option.
    • Season 4 appears to be running on this, especially the episode "Prophets".
  • The Producer Thinks of Everything: when the camera focuses on Root's earpiece in "Aletheia", you can hear high-pitched beeping that sounds like Morse code. If you're under 40, that is. Guess how the Machine contacts Root without Control noticing.
    • Remember, Amy Acker is 37. Camryn Manheim is 52.
  • Rewatch Bonus: There's a lot of things that you probably won't catch the first time around. Or even the second time around!
  • Rescued from the Scrappy Heap: Carter was initially the Base Breaker when the show began. However her evolution into The Chessmaster in "Endgame" was met with favourable responses from fans and critics alike. This may have contributed to a portion of the fan base having a highly negative reaction to her demise in "The Crossing".
  • The Scrappy: Wayne Krueger, one of the most unsympathetic persons of interest on the show to date. This was very much an Intended Audience Reaction. Depending on the portion of the fanbase we're talking about, Root may qualify.
  • Single-Issue Wonk: The death of Carter has turned a huge portion of the fan base into these.
  • So Cool It's Awesome: A lot of what Team Machine pulls off on an episode by episode basis falls into this category.
  • Special Effects Failure: The show has largely stopped using blank-firing guns in exchange for nongunsnote  or non-firing props with muzzle flashes added in post production. It can bother viewers who are familiar with firearms, especially when muzzle flashes go off when characters clearly have their fingers off the triggers.
  • Squick: How Ulrich Kohl uses needles in "Foe."
    • And then The horrifying ear surgery/interrogation Control does to Root.
  • They Changed It, Now It Sucks: The move away from the formulaic crime procedural format(like NCIS, NCIS LA and Hawaii Five-0) and increased emphasis on the serialized science fiction aspects of the show have caused this big time on the Shows Facebook page alienating the traditional CBS procedural fans who preferred the show when it still was in the former format.
  • Unpopular Popular Character: Fusco, all the way. He's one of the more sympathetic characters in the show, and a genuine atoner, but the universe keeps piling more and more shit on him. However, things have begun to look up for him since his promotion and now he's a hero in the eyes of most of his NYPD colleagues. Although from time to time he still gets some ribbing from the other members of Team Machine.
  • The Untwist: Carter's new partner Laskey does turn out to be a member of HR. It was so obvious that Carter herself picked up on it the minute she met him and used this against him.
  • Vocal Minority: The show's Facebook page has a large number of posts with a negative opinion of Shaw and Root. This has been made worse by the death of Carter.
