* 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.
* AssPull: Season 2, episode 9. See JumpingTheShark
* BaseBreaker: Annie Blackburn. While she isn't without her fans, she still gets flack from [[FanPreferredCouple Cooper/Audrey]] shippers.
** [[TheScrappy John Justice Wheeler on the other hand...]]
* 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.
* 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 it's 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.
* 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.
** It's rumoured that the decision not to move forward with the Cooper and Audrey romance was down to Lara Flynn Boyle (who was involved with Kyle at the time). It was confirmed by the producer-writer Robert Engels.
* 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=]''.
* HollywoodHomely: David Lynch lampshades this in-character:
-->'''Gordon Cole''': "This world of Twin Peaks seems to be filled with beautiful women!"
* HolyShitQuotient: Extremely high.
* [[GermansLoveDavidHasselhoff Japanese Love Twin Peaks]]: While ''Twin Peaks'' is more along the lines of a [[CultClassic Cult Classic]] in the U.S., it was VERY popular when it aired in Japan. It even influenced the creators of [[TheLegendOfZeldaLinksAwakening a popular Nintendo game you may have heard of]].
** 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&feature=related here]]
** VideoGame/DeadlyPremonition is a spiritual adaptation.
* 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.]]
* JumpingTheShark: Episode 9 of the second season. [[spoiler:This is the episode where they solve the Laura Palmer case. In one day. It opens with a conversation leading to Coop acting extremely and blatantly OutOfCharacter and telling the police to "Give (him) twenty-four hours to solve this case," and [[AssPull they solve the whole case]] through Cooper remembering Laura in his dream saying, "My father killed me."]]
* MemeticMutation: "She's dead... wrapped in plastic."
** [[OminousOwl "The Owls are not what they seem."]]
*** ''TwinPeaks'' is [[Memes/TVTropes currently a running joke]] on the TVTropesFora, 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.)
* OneSceneWonder: Loads of these in the movie. DavidBowie shows up for all of a minute as Agent Jeffries (whose role in the shooting script was slightly larger), Harry Dean Stanton as a bizarre trailer park landlord, etc.
** Jimmy Scott only shows up in the last episode -- in one of the most haunting scenes in the series.
* 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!"]]
** [[TwoWordsObviousTrope Three words:]] 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.
* TheScrappy: James Hurley (for being 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. Annie and John Justice Wheeler, especially if you're a [[FanPreferredCouple Cooper/Audrey]] fan.
** Lana Budding Milford also gets a lot of flack.
** Arguably the series' biggest Scrappy is Evelyn Marsh, who served no purpose to the main storyline and was probably only added to [[spoiler:[[PutOnABus write James off the show]]]].
* 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.
* SignatureScene: The Red Room scene at the end of the third episode.
** The image of Laura's body wrapped in plastic from the first episode became iconic of the show also.
* 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.
