* AlternativeCharacterInterpretation:
** Is Dale Cooper a [[IncorruptiblePurePureness good guy]] or is he not or at least by the prequel... [[NarniaTime urh sequel]]? ''Fire Walk With Me''. With Phillip Jeffries we saw what the [[EldritchLocation Black Lodge]] can do to a man. In the film Future!Dale warns Laura from taking the ring, while taking it ensures her death it protects her from being possesed by [[TheCorrupter BOB]] who has been catering her for years by that point, if Laura doesn't takes the ring she doesn't die, but she gets consumed by BOB; that means that Dale doesn't have to go to Twin Peaks and get send to the Lodge. Was he trying to save Laura or trying to do a temporal fix and [[DirtyCoward save his own ass at Laura's innocence expense]]?
** Is the Man From Another place [[spoiler:legitimately trying to stop BOB to prevent a catastrophe from happening, or is he an evil spirit trying to take control of BOB for his own purposes?]] Due to the show's cancellation, we may never know for sure.
** His motivations remain mysterious in the show, but ''Fire Walk With Me'' lends a darker interpretation to his character. [[spoiler:He seems opposed to BOB only in that BOB hoards garmonbozia for himself and deprives the other Lodge creatures of their rightful fill. The Man From Another Place is happy to slurp up the garmonbozia that BOB proffers after killing Laura and thereby inflicting suffering upon both Laura and Leland.]]
** Further related to ''Fire Walk With Me'', [[spoiler:he claims to be "the arm," (likely) meaning Mike's arm - a remnant of Mike's own evil. I've always thought that the Black Lodge denizens were unhappy with BOB running amuck after Mike turned good. (If BOB was Mike's familiar, he probably had him on something of a leash.) BOB wasn't paying his garmonbozia taxes, so the MFAP and "Mrs. Tremond" etc. were therefore helping the investigation of who killed Laura more than they might have otherwise.]]
** There are a couple of possible interpretations for [[TheSkeptic Albert]]'s involvement in [[OccultDetective Blue Rose]] cases as authorized by Gordon Cole. One is that it's necessary to have a skeptic on board so that the more supernaturally-attuned agents don't go too far in suggesting or pursuing supernatural explanations where there may be none, and Albert helps pull them back down to reality where necessary. Another is that in cases that ''do'' involve the supernatural, his lack of sensitivity to spiritual or supernatural matters makes him a less likely victim or target, with those who ''are'' more inclined toward less empirical and more spiritual/supernatural explanations (such as Cooper) serving as DesignatedPointMan: this in turn would allow Albert to keep the necessary investigation ongoing and to serve as a witness if it falls through (which ''The Secret History of Twin Peaks'' implies is also T[[spoiler:amara]] P[[spoiler:reston]]'s role). If the latter of these explanations, Albert might be considered to have the sixth sense equivalent of a DisabilitySuperpower.
** Is Denise Bryson a male {{Transvestite}}, or a {{Transgender}} woman? The show never clears it up, as LGBT issues weren't as well understood in 1990 (at least, by those outside the community). The 2017 revival definitively states that she's a transwoman.
*** Can also be a shout-out John Edgar Hoover if he was in 2017.
** Even some of the minor and one-off characters are subject to debate. For instance: "Do you want to hear about our specials? ''We don't have any!''" TheMovie leaves it very vague as to whether these are the words of a DeadpanSnarker or an outright CloudCuckoolander.
%%* AssPull: Season 2, episode 9.
* BaseBreakingCharacter: Annie Blackburn. While she isn't without her fans, she still gets flack from [[FanPreferredCouple Cooper/Audrey]] shippers.
* BetterOnDVD: While it's fine on its own, most episodes seem to make up a single day of investigation. Some details from the first few days come in a little later, when you might have forgotten about it.
* BigLippedAlligatorMoment:
** Season 2 episode 8 has a flashback of Ben and Jerry remembering a girl dancing around with a flashlight in their room as children. It's wordless, 4 frames per second, and goes on for over a minute. Hold on, Ben & Jerry?... [[LateToThePunchline Oh lord.]]
** The singing scene with James, Donna and Maddy. Helped heaping them all onto the [[TheScrappy scrappy heap]] if they weren't there already.
** As [[MindScrew bizarre]] as the dream from "Zen, or the Skill to Catch a Killer" was, every element of it ends up returning and being important to the plot -- with the exception of that shadow that passes behind the curtain.
*** Or is the shadow an exception at all? It looks an awful lot like the outline of a certain ring (viewed from above) that shows up in FWWM, which is heavily implied to be related to the Man From Another Place...
** Ben Horne losing his mind for a few episodes and dragging his family into civil war reenactments. Any explanation they gave would probably cause more questions than answers.
* BrokenBase: Despite season 3 receiving nearly universal praise from fans and has been cited as the best revival of the revival craze, there's still some things the viewers can't get along.
** Some didn't like the full fantastic plot of the new season and said it destroyed the ambiguous interpretations of the original [[spoiler:like Sarah Palmer's visions being the result of the drugs Leland gave her to sleep when he raped Laura, Laura hallucinating due to trauma, or Leland just repeating the behavior he received when sexually abused as a kid by a man named Bob.]] while the rest of the fanbase prefer it ''because'' of how surreal it is, and for providing some definite answers.
** For those who had any expectations to the new series and wanted the light hearted [[spoiler: by comparison]] feel of the original, or those who wanted it to be darker, especially those who still consider Fire Walk With Me as the DarkerAndEdgier installment of Twin Peaks with the new season just being BloodierAndGorier at best, or just plain rauchier at worst.
%%* TheChrisCarterEffect
%%* CommitmentAnxiety
* CompleteMonster: [[AxCrazy Killer BOB]] ([[RecursiveAcronym Beware of BOB]]) of the [[spoiler:[[EldritchLocation Black Lodge]] was once a vicious SerialKiller who liked to rape and murder young women. Since his death, [[SlasherSmile BOB]] became something more. An inhabitant of the Black Lodge, [[KnightOfCerebus BOB]] accesses the material plane by [[DemonicPossession possessing hapless humans]] and forcing them to commit murder, rape and general horror in order to delight and nourish himself. Responsible for the murder of Laura Palmer that drives the series, [[BigBad BOB]] committed the deed by possessing Laura's father Leland when Leland was a child, resurfacing to have Leland [[ParentalIncest molest his own daughter]] through her youth before using him to finally rape and murder Laura. When cornered, BOB forces Leland to kill himself. Ending the series by [[KarmaHoudini possessing the hero Agent Cooper]] and [[EvilLaugh laughing maniacally]] after appreciating his healthy, handsome young body, BOB remains one of the most twisted products of even Creator/DavidLynch's mind.]]
* CreatorsPet: David Lynch liked Joan Chen's performance, which is why she gets a lot of focus despite not being very popular with fans.
* CreepyAwesome: The Black Lodge in general, the Man From Another Place and BOB in particular.
* [[SugarWiki/AwesomeMusic Crowning Music of Awesome]]: The soundtrack, really. Good thing too, because most of it consists of a few tracks played over and over in each episode, and if it weren't so good it would drive people crazy. Now has [[AwesomeMusic/TwinPeaks its own page]].
%%* CultClassic
* EnsembleDarkHorse:
** Audrey is one of, if probably not THE most popular character aside from ol' Coop.
** Gordon Cole, Albert Rosenfield, and Maddie Ferguson all have pretty big fanbases despite not appearing that much.
* FairForItsDay: Denise is portrayed by a cis man and it's never quite clear whether she's a male crossdresser or a transgender woman. However, she is treated with a surprising level of respect and Cooper has no problem accepting her.
* FanPreferredCouple: The Cooper and Audrey pairing was preferred not only by fans, but by Lynch himself; explicit references were written out of the script at Kyle [=MacLachlan=]'s objection to their relationship. Both were later given other (and fan-reviled) love interests in the second season.
* FriendlyFandoms: Name anything that cites ''Twin Peaks'' as an influence, and odds are, its fans get along pretty well with the ''T.P.'' fandom. ''VideoGame/DeadlyPremonition'', ''WesternAnimation/GravityFalls'' (and by extension, the entire "Mystery Kids" fandom, which extends to ''WesternAnimation/{{Coraline}}'', ''WesternAnimation/InvaderZim'', ''WesternAnimation/{{Paranorman}}'', ''VideoGame/{{Psychonauts}}'', and ''WesternAnimation/ScoobyDooWhereAreYou'', among others), ''Podcast/WelcomeToNightVale'', and ''Series/TheXFiles''.
* GermansLoveDavidHasselhoff: While ''Twin Peaks'' is more along the lines of a CultClassic in the U.S., it was VERY popular when it aired in Japan. It even influenced the creators of [[VideoGame/TheLegendOfZeldaLinksAwakening a popular Nintendo game you may have heard of]] and [[Franchise/SilentHill a certain long-running video game series by Konami]].
** Lynch even filmed a series of Japanese coffee commercials, starring Agent Cooper and the rest of the gang. Can be seen [[http://www.youtube.com/watch?v=3A_-FHsPwfQ here]]
** VideoGame/DeadlyPremonition is a spiritual adaptation.
* HarsherInHindsight: The 2017 revival was filmed at the exact right time, with ''three'' major actors (Catherine Coulson, Miguel Ferrer, and Warren Frost) living just barely long enough to be part of it. This also makes the 25 year prediction in the finale even more eerie.
* HeReallyCanAct: Creator/MatthewLillard's performance in ''The Return'' has been pretty well-recieved, especially with people who were only familiar with him as [[Film/ScoobyDoo Shaggy]].
* HilariousInHindsight:
** Creator/DonSDavis being part of a secret military project involving aliens years before [[Series/StargateSG1 being part of a secret military project involving aliens]] is hilarious on its own, but the best part is when he advises Cooper against keeping secrets for the sake of the greater good, which was the crux of a lot of drama and the opposite stance he and most of the cast took on ''[=SG1=]''.
%%** "[[UnCanceled I'll see you again in 25 years]]."
* HollywoodHomely: David Lynch lampshades this in-character:
%%* HolyShitQuotient: Extremely high.
* ItWasHisSled: Mostly averted, but those who have never seen the show should still be wary of spoilers. Many fans who saw it when it first aired believe the show is now too old for anything to be a spoiler, despite the fact that many new fans, too young to have seen it the first time, are trying to catch up in preparation for Season 3 (or because they became curious after playing ''Deadly Premonition'').
* JerkassWoobie: [[spoiler:Leo arguably becomes this over the course of his captivity in Windom Earle's cabin, during which he comes to understand firsthand the sort of horrifying abuse he inflicted upon Shelly. See RedemptionEqualsDeath below.]]
* MemeticMutation:
** ''Series/TwinPeaks'' is [[Memes/TVTropes currently a running joke]] on the Administrivia/TVTropesForum, where it is regularly mentioned among anime. (The reason for this is that someone once recommended this in an anime recommendations thread where the original poster didn't explicitly ask for anime.)
** "She's dead... wrapped in plastic." (said about Laura Palmer)
** [[OminousOwl "The Owls are not what they seem."]] (ArcWords from the Giant)
** "It's happening again." (originally referring to [[spoiler: BOB!Leland murdering Maddie Franklin as a repeat of his rape/murder of her identical cousin, Laura Palmer]], this has become a tagline for The Return.)
** "James was ''never'' cool" and variations became popular after the [[TheScrappy infamous character]] was described as "still cool" in The Return.
* {{Narm}}: James, Donna and Maddie singing a cheesy song whose lyrics are "Just you and I... together... forever...". The song is heard again later when Donna is looking for James to the same effect.
* OneSceneWonder: Jimmy Scott only shows up in the last episode -- in one of the most haunting scenes in the series.
** [[Creator/MichaelCera Wally Brando]], [[spoiler:Andy and Lucy's grown child]] is already gaining this reputation, based solely off of his [[http://www.vulture.com/2017/05/michael-cera-twin-peaks-cameo-watch.html bizarre, stilted monologue]] delivered in Episode 4 of the revival.
* PairTheSpares: There is a small following for Annie Blackburn x John Justice Wheeler. The two never even meet, but Dale x Audrey shippers sometimes like to pair their respective replacement love interests together, just so Dale and Audrey can become a couple again.
* ReplacementScrappy:
** Annie Blackburn, who was wheeled in out of nowhere purely to supplant Audrey as Cooper's love interest. Her [[spoiler:winning the Miss Twin Peaks pageant]] is likely to produce the same reaction from viewers that it did from [[spoiler:Mayor Milford: "She's been living in this town about fifteen minutes!"]]
%% ** John Justice Wheeler.
* RescuedFromTheScrappyHeap: Almost. After spending Season One as a weak-willed pawn being manipulated by Catherine and Ben Horne before running crying to Sheriff Truman, it is revealed that Josie [[spoiler: has secretly been working with Ben to frame Catherine for the mill fire, and also had a hand in her husband's death, which gave her the mill in the first place.]] Then, in the following season, it is discovered that Josie did all this at the behest of another person, turning her back into the easily manipulated victim. One step forwards, two steps back.
* RomanticPlotTumor: Several. Primarily to blame for the general consensus that the second season would've been much better if it had been half as long.
* RetroactiveRecognition: Yes, that's a pre-''Series/TheXFiles'' Creator/DavidDuchovny as Denise Bryson.
* TheScrappy:
** James Hurley (for being [[TheDitz monumentally stupid]], even by the standards of Twin Peaks teenagers) and Josie Packard (for being a hysterical victim and nothing else); take your pick. Or Nadine (although some more recent fans love her for her eerie resemblance to CrazyAwesome secret agent Molotov Cocktease from ''TheVentureBrothers''). Annie and John Justice Wheeler, especially if you're a [[FanPreferredCouple Cooper/Audrey]] fan.
** Evelyn Marsh, who served no purpose to the main storyline and was probably only added to [[spoiler:[[PutOnABus write James off the show]]]].
%%** Lana Budding Milford also gets a lot of flack.
* SeasonalRot: It is generally agreed that the series loses focus after the main story arc is resolved in episode 8 of season 2. A new, related story arc emerges in the rest of the second season, but much of it suffers from having been neglected by Lynch and left to less competent writers and directors, causing [[DependingOnTheWriter a vast drop in quality and major inconsistencies in characterization]]. Kyle [=MacLachlan=] became impatient with Lynch's non-involvement and cast member Kimmy Robertson admits to having stopped watching due to SeasonalRot. There is, however, also general agreement about that the series (if only barely) managed to avoid JumpingTheShark and actually found some of its original form again in the final episodes of Season 2.
* SignatureScene: The Red Room scene at the end of the third episode. Apart from a famous reference to this scene in the two-part "Who Shot Mr. Burns?" episode of ''WesternAnimation/TheSimpsons'', both ''WesternAnimation/GravityFalls'' and ''WesternAnimation/ScoobyDooMysteryInc'' have done explicit ShoutOut scenes to it, with ''Mystery Inc.'' even having a dog stand-in for Laura, and getting the same actor for The Man From Another Place!
** The image of Laura's body wrapped in plastic from the first episode also became iconic of the show.
* SpecialEffectFailure: The cup in the Black Lodge in the final episode that changes from a liquid, to a solid, and back to a very viscous liquid again. Upon closer inspection the solid tea is just a lump of plastic.
* StrangledByTheRedString: Both Cooper/Annie and Audrey/Jack are viewed this way by a sizable amount of the fanbase.
%%* UncannyValley: Everything about the Black Lodge.
%%* VillainDecay: Ben.
* TheyChangedItNowItSucks: Averted somewhat with The Return. Gone is the campy, soap opera-like humor and quirkiness of the first 2 seasons. The new episodes are much more darkly comedic and unnerving, sharing thematic elements with some of Lynch's film work such as ''{{Film/Eraserhead}}'', ''Film/LostHighway'', ''Film/MulhollandDrive'' and ''Film/InlandEmpire''. While you would expect this to turn off fans of the original seasons, this doesn't seem to have affected the hype and enthusiasm not one bit.
* {{Wangst}}: Done intentionally with Leland in season 1.
* WhatAnIdiot: Laura is a tragic example, Andy is a comic one, and Maddy, James and Bobby are just dumb.
%%* TheWoobie: A good chunk of the characters, actually.
