* AlternativeCharacterInterpretation:
** 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 LGBTQIA issues weren't as well understood in 1990 (at least, by those outside the community).
** 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.
%%* TheChrisCarterEffect
%%* CommitmentAnxiety
* CompleteMonster: [[AxCrazy Killer BOB]] ([[RecursiveAcronym Beware of BOB]]) of the [[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.
* [[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 transvestite 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.
* HilariousInHindsight:
** Don S. Davis 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:
-->'''Gordon Cole''': "This world of Twin Peaks seems to be filled with beautiful women!"
%%* 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."
%%** [[OminousOwl "The Owls are not what they seem."]]
* {{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.
* 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 became iconic of the show also.
* 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.
* {{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.
