These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
This show also does not hold the federal government's institutions like the FBI and CIA in high regard. To be fair, 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.
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.
Adult Fear: Extremely common in the show. A noticable example is in "Flesh and Blood" when Finch reveals to Simmons that Elias has implemented a contingency to kill off the families of HR members. As Even Evil Has Loved Ones, Simmons yanks the support he was giving to Elias.
Base Breaker: To put it bluntly, Person Of Interest's fan base is highly volatile with many strong opinions about characters.
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.
And now multiple fans of the show are up in arms over the final moments of "The Crossing".
Big Damn Kiss: There is heated debate going on amongst the fans about whether Reese kissing Carter during "The Crossing" was a romantic gesture or merely a way of thanking her just before he risks his life to distract the HR cops and criminals who are chasing them so she can complete her operation to destroy HR.
Fan Dumb: Despite Jonah Nolan repeatedly mentioning that an important character would die during the three episode event "Endgame", multiple fans on twitter and forums have declared that they would no longer watch the show solely due to Carter's passing and have been suggesting ways in which Carter could be brought back to life
From looking at the show's Facebook page, Shaw and Root get a lot of unjustified backlash.
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'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"
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.
Jonathan Nolan: Turns out the only thing that’s science fiction about our show is the public outcry that we imagined if anyone found out about Finch’s 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%.
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 (If not, pretty much all you'd have to do is suggest it and someone in the fandom would make it happen.) Most of them are crack pairings, but some of them are actually pretty popular.note Leon Tao and Logan Pierce? Shaw and Cal Beecher? Szymanski and Donnelly? Nathan Ingram and Kara Stanton? Root and Everyone? Yes, those are all ships.
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.
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."
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.
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 organisations.
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 multiple innocent citizens to their deaths, in order to get to Nathan Ingram.
Word of God in "Fleet Week", 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.
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.
Relationship Upgrade: A popular interpretation of the interaction between Reese and Carter during "The Crossing" is this.
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".
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
"Well Done, Son!" Guy: The machine's relationship with Finch. It sets him up with his Fiancée, saves his life and tries to look out for him and make him happy. Harold's response? Program it with a code which causes it to literally kill itself every day in order to stop developing a personality.
Why Fandom Can't Have Nice Things: The reaction to the ending of "The Crossing" has forced the show runners and Taraji P. Henson to go into something akin to damage control mode.
Taraji P. Henson: "That's why people are so distraught today. And that's what art is supposed to do: It's supposed to make you feel. You're supposed to be mad and want to throw a glass and yell, "Goddammit, I'm not going to watch this show again." We did our job."
