* AccidentalInnuendo: Molly tells Sherlock that if he ever needs help, he can "have her." And later on, Sherlock says he "needs" Molly though he means [[spoiler:he needs her help to fake his death]].
* AngstWhatAngst: John Watson seems to have PTSD in the first episode to the extent he'd developed psychosomatic ''pain''... but gets over it pretty quickly. Somewhat justified as being away from the war is what's causing his issues. Getting back to adventure solves that nicely.
** Although as the FridgeBrilliance page shows there is the implication he didn't get over it, a subtle one but it's certainly there.
*** [[spoiler: And the subtlety goes out the window as of ''His Last Vow'', where it's revealed that John's [=PTSD=] has evolved into a danger addiction that has completely wrecked his ability to live a normal life.]]
** Mrs. Hudson casually mentions how she found out her husband was a drug dealer and a murderer then rants how their relationship was [[GettingCrapPastTheRadar mostly physical.]]
* AwardSnub:
** The show received 4 noms for the first run of episodes, but failed to earn recognition for the top prize or for its performances. Notably Steven Moffat lost the award for Best Screenplay for a TV Movie or Mini-Series to ''Downton Abbey'' (whose writer Jullian Fellowes had already won an Oscar about 9 years earlier). This is especially egresious since Downton Abbey has been shifted from the Mini-Series category to the Drama Category for all of its subsequent seasons.
** ''Sherlock,'' its cast, and crew were nominated for thirteen Emmy categories in 2012 for Series 2, but won none of them. Naturally, rage from the fans ensued.
** Series 3 aired too late to qualify for the 2014 National Television Awards. But somehow, reruns qualified, and Benedict Cumberbatch won the new Best TV Detective category. The trope was averted this time despite no new episodes airing!
** Averted for Series 3: Out of its four 2014 Emmy nominations, it won three: best actor, best supporting actor, and best writing (all in the miniseries/movie category).
* AwesomeEgo: Sherlock himself. Moriarty could count as a villainous example.
** To a lesser extent, Charles Augustus Magnussen. He's a disgusting sociopath, but [[spoiler:if you had a mind capable of storing countless facts in your head and could easily recite them from memory, and could do a SherlockScan as well as the great man himself]], wouldn't you also find it hard to brag? [[spoiler:Deconstructed as his having no backups allows Sherlock to easily shoot him in the head]].
* BaseBreaker:
** Initial reactions to the camp Moriarty seem to range from 'obnobxious voice and looks like a twelve-year old' to 'deliciously creepy re-interpretation similar to the newer versions of [[Series/DoctorWho the Master]] and [[Film/TheDarkKnight the Joker]]'
** Interestingly enough, [[Film/TheDarkKnight the Joker]] comparisons are used by both Moriarty's fans and detractors.
*** Then there's the whole split of Moriarty fans who believe he is delightfully fucked up in contrast to the fans who manage to both [[DracoInLeatherPants leather pants him]] and [[{{Wimpification}} wimpy-fy]] him while saying [[AlternativeCharacterInterpretation "My poor baby!"]]
** The fan reactions to Irene Adler are contrasting at best. Either she's a clever, competent woman who managed to best the great Sherlock Holmes, or her character was oversexualised and reduced to a DamselInDistress at the end. Not to mention how the hate for her can reach ''well'' into RonTheDeathEater territory.
** As of His Last Vow, the fandom seems split over John's reaction to [[spoiler: Mary's secret.]] While some fans think it shows [[spoiler: his dedication and love,]] others think he's [[spoiler: only staying with her because of the baby.]]
* BrokenBase: Pretty much all of Series 3 is subject of the debate, we half the base calling it brilliant and the others calling it horrible. No, [[spoiler: Moriarty's supposed return]] hasn't helped matters. Then there are fans who think that season 3 is both brilliant and horrible. And even some who think it's merely good.
* ComplainingAboutShowsYouDontWatch: A fair few "professional" reviewers initially did this. And still a few people won't watch it based solely on premise.
* CompleteMonster: [[ManipulativeBastard Jim]] [[TheChessmaster Moriarty]] is the world's only [[PsychoForHire "consulting criminal,”]] a man hired by various people who need his genius to help them commit their own crimes. [[BigBad Throughout the series, Moriarty]] turns a dying, old man into a SerialKiller in "[[Recap/SherlockS01E01AStudyInPink A Study in Pink]]" by promising to pay money to his children for each person he kills, manages to sneak [[TheTriadsAndTheTongs the Black Lotus organization ]]into London in "[[Recap/SherlockS01E02TheBlindBanker The Blind Banker]]" [[YouHaveFailedMe then kills their leader when she fails in her task]], and sells information to terrorist cells. [[ForTheEvulz He does all of this to distract himself from his boredom]] [[AttentionWhore and catch the attention of Sherlock Holmes]]. In the first season's finale "[[Recap/SherlockS01E03TheGreatGame The Great Game]]", Moriarty decides to play a little "game" with Sherlock, selling out his clients and challenging Sherlock to solve the crimes they committed. For incentive, he kidnaps people, [[WouldHurtAChild including one young child]], and straps bombs to them which will detonate if Sherlock doesn't solve the crimes in the allotted time. When one of his victims, a blind, traumatized, old woman only begins to describe the sound of Moriarty's voice after Sherlock solves the case, Moriarty detonates the bomb, killing her and eleven others. In the second season finale "[[Recap/SherlockS02E03TheReichenbachFall The Reichenbach Fall]]", Moriarty sets about his plan to destroy Sherlock's reputation and life utterly. He pulls of several heists, and escapes justice by threatening the jury. He has a man that looks just like Sherlock kidnap the seven and nine-year-old children of the Ambassador to America, [[YouHaveOutlivedYourUsefulness then kills his accomplice after he outlives his usefulness.]] He then feeds the children chocolate laced with mercury to kill them if Sherlock can’t find them. In the end, after framing Sherlock as a master criminal who committed both the crimes Moriarty was blamed for and the cases Sherlock himself solved, Moriarty threatens to set his assassins on Sherlock's only three friends in the world, John Watson, Greg Lestrade, and Mrs. Hudson, if Sherlock doesn’t commit suicide. Moriarty was ultimately a man so committed to winning his "game" with Sherlock, that when Sherlock points out as long as Moriarty's still alive, he can force him to call off the assassins, Moriarty responds by [[spoiler:[[AteHisGun merrily eating his gun to give Sherlock no choice but to kill himself.]]]] Moriarty was [[EvilCounterpart the dark reflection of Sherlock:]] a sociopathic genius that would [[TheUnfettered let nothing stand in his way to escape from his excruciating boredom.]]
* ConsolationAward: A more cynical interpetation for Sherlock's surprise 2014 Emmy sweep.
* CrazyAwesome:
** He's ''Sherlock Holmes'', and crazier than most portrayals. He keeps eyeballs in the microwave and a severed head in the fridge, and gets rid of boredom by spray-painting a smiley face on the wall and shooting at it. And the thumbs in the refrigerator. Poor Mrs. Hudson.
*** Bonus points for shooting the wall ''being canon'' to the source material- in "His Last Bow", he shot the Queen's initials into his wall as target practice.
** Also Mycroft in his own way. His use of phones and CCTV cameras is quite impressive.
** Moriarty.
* CreepyAwesome: Sherlock, again.
** Sherlock does this too many times to count, but particularly this interaction in "A Study in Pink", immediately after [[{{Crosses the Line Twice}}another foot-in-mouth moment]]:
--->'''Sherlock:''' If you were dying, if you'd been murdered, in your very last seconds what would you say?
--->'''John:''' Please, God, let me live.
--->'''Sherlock:''' Oh, use your imagination!
--->'''John:''' I don't have to.
*** Moriarty, even more.
** Magnussen, owing to his DangerouslyGenreSavvy moments coupled with him being an absolute creep.
* CriticalResearchFailure: Sherlock repeatedly insists he's a "high-functioning sociopath", which [[http://io9.com/5933869/stop-calling-sherlock-a-sociopath-thanks-a-psychologist he evidently is not]]. May or may not be justified as an extremely poor self-diagnosis. This is the man who doesn't know the Earth revolves around the sun, after all.
* DieForOurShip:
** Averted with Molly. Despite the HUGE slash fandom that this show has, Molly doesn't have much of a {{Hatedom}} mainly because she's just so damned ''adorable'' (and to a lesser extent, as Moffat's personal ChewToy, so damned pathetic, no one really has the heart to hate her.)
** Irene also survived the shippers relatively unscathed. Mainly because, despite the enormous amounts of FoeYay, she's also a ShipperOnDeck.
** Both Averted and Played Straight with Mary. Many fans were annoyed that Mary would show up and hoped for her eventual demise, but reaction to her has been good so far. It helps that she's sweet, funny, likes Sherlock and has great chemistry with John (being played by Martin Freeman's real-life partner).
** Worth mentioning that, after His Last Vow, many people are, once again, looking forward to Mary's eventual demise.
* DracoInLeatherPants: Moriarty. Depite being [[CompleteMonster irredeemable]] in the show he gets this treatment in fandom for being attractive and funny.
** His Irish Accent is enough to give non-fangirls of him ''instant nosebleeds'' (but only if they're listening on earphones or headphones.)
** Averted with fanfics about Kitty Reilly getting a new chance, as most writers enjoy letting her feel colossal amounts of guilt in the beginning.
* EnsembleDarkhorse:
** Mycroft. That's what you get when you utilize the character's full MagnificentBastard / SharpDressedMan potential and cast [[spoiler:Mark Gatiss]] in the role.
** Not to mention his assistant, "[[SexySecretary Anthea]]". Five lines, two scenes, one episode, and ''no'' real name revealed for her... and the fandom absolutely ''adores'' her. Needless to say, her return, however brief, in ''The Empty Hearse'', was met with much rejoicing.
** Molly Hooper was originally intended to be a one-off character, but she quickly became a favorite among the creators and the fans.
** Mary Morstan is absolutely loved by the fandom. Or was, up until ''His Last Vow'', at least.
** Mrs. Hudson is also a fan favorite.
** Lestrade is well liked by the fandom as well.
** Archie from "The Sign of Three".
* EvenTheGuysWantHim/[[EvenTheGuysWantHim Even Lesbians Want Him]]: Sherlock, according to some interpretations of the conversation between John Watson and Irene Adler.
* EvilIsSexy: Moriarty, plus with a healthy dose of Westwood Suits and EvilIsHammy to come with it.
* FandomRivalry: Oh, where to ''begin''.
** For one, there's the [[Film/SherlockHolmes 2009 and 2011 Guy Ritchie films]].
** Brief kerfuffles in early 2012 with the fandom of the KPop band SHINee, for overtaking the #Sherlock tag on Tumblr for the band's new album.
** Fights with ''Series/{{Elementary}}'' fandom have naturally gotten ''ugly'', mainly for Watson's GenderFlip and RaceLift. And, ironically, Sherlock fans flooding the Elementary tag on Tumblr.
** The 2013 National Television Awards have made enemies of DowntonAbbey fans for winning over Sherlock. Cue more tag-flooding on Tumblr...of the wrong tag.
** Fights got nasty with ''Series/TeenWolf'' fandom on Tumblr, in March 2013. ''Series/TeenWolf'''s Season 3 airdate was posted by a fan, but only mentioned the show in the tags. Fandom outrage, once again, as confused Sherlockians thought they were being deliberately misled.
* {{Fanon}}:
** As of this writing, it hasn't even been officially confirmed that Sebastian Moran will appear in this show at all. Though browsing the insane amounts of [[http://browse.deviantart.com/?q=sebastian+moran Modern!Moran fan art]] on Website/DeviantArt might give you a different impression.
*** A Lord Moran appears in the first episode of Season 3, though that seems to be where the similarities end. [[spoiler: The true Sebastian Moran is seemingly ''Mary Morstan'' of all people, who is something of a CompositeCharacter.]]
* FanPreferredCouple: Holmes/Watson of course.
** Supposedly this doesn't stop with the fans; [[OneOfUs the creators and writers ship it too]].
** Mycroft/Lestrade and Moran/Moriarty -- although the former hasn't yet been confirmed to exist in-universe -- have become quite popular as well.
** Sherlock/Adler, which is a ship that started [[OlderThanTelevision waaaaaaay back in the original books]], is still going strong, with lots of supporters.
* FoeYay:
** Sherlock and Moriarty, naturally. Moriarty calls Sherlock 'sexy', the dance between them 'flirting', and so on. Almost all one-sided though, due to [[spoiler: the deliciously camp re-imagining of Moriarty]].
** Sherlock and Irene Adler too.
* FourthWallMyopia: Donovan suffers from the effects of this. ''We'' know that Sherlock isn't going to turn evil, but she doesn't.
* FriendlyFandoms: With ''Series/DoctorWho''. Both shows share showrunner Creator/StevenMoffat (Moffat took over as showrunner for ''Doctor Who'' in 2010, the same year ''Sherlock'' premiered), and there are a decent amount of crossover fanworks between the two, most notably [[http://www.youtube.com/watch?v=q3bGYljQ5Uw this very well made special effects mash up of the Eleventh Doctor inviting Sherlock to be his next companion]]. Fans of both shows have even come up with the crossover name "Wholock."
** These fandoms are also friendly with that of the American television series ''{{Series/Supernatural}}'', to the point that the combined fandoms have been dubbed "Superwholock".
** Also on good terms with fans of the ''Film/TheHobbit'' films, where both Creator/MartinFreeman ''and'' Creator/BenedictCumberbatch play starring roles.
** There's also the ''Franchise/StarTrek'' fandom (namely the [[Film/StarTrek reboot]] [[Film/StarTrekIntoDarkness series]]) due to Cumberbatch's involvement with the franchise. Hell, his character even dresses like Holmes at certain points in the second film as well.
* FunnyAneurysmMoment: From the first episode:
-->'''John:''' Do people usually assume you're the murderer?
-->'''Sherlock:''' Now and then, yes.
** There's actually dozens of these if actually look close enough [[spoiler: especially references to "The Reichenbach Fall"]]. It seriously adds to the rewatch value.
** This line from John's blog, regarding an incident between Sherlock and himself in ''Baskerville''- [[spoiler: He'd used me as an experiment. One day I will kill him.]]
** When John wanders past a [[spoiler:dummy hanging by the neck from the ceiling of 221B,]] he jokes, "So... did you just talk to him for a very long time?" [[spoiler:Incredibly harsh when you consider that, after Jim Moriarty talked to him for a very long time, Sherlock apparently committed suicide before the end of the episode. Ouch.]]
* GeniusBonus: The StandardSnippet to which [[spoiler:Moriarty]] commits the heist of the century in ''[[{{Recap/SherlockS02E03TheReichenbachFall}} The Reichenbach Fall]]''? The Overture to Rossini's ''La Gazza Ladra'', or '' The Thieving Magpie''. Doubles as a ShoutOut to ''Film/AClockworkOrange''.
* GermansLoveDavidHasselhoff: The show is popular in many countries across the globe from America to India but none of them are as obsessed with it as China is. There is even a Sherlock themed cafe in Shanghai.
** Johnlock fanfiction is becoming increasingly popular in China, and even non-shippers agree that they have a epic bromance. Tie-in editions also tend to sell out faster than other editions of the canon there, and many fans also enjoy the Casebook.
* HarsherInHindsight:
** The first episode. Sgt. Sally Donovan says: [[spoiler:"One day we'll be standing around a body and Sherlock Holmes will be the one who put it there."]] Fast forward to "The Reichenbach Fall" and ''ouch''.[[note]]Sherlock "committed suicide" as part of a ThanatosGambit by Moriarty, so technically there is a body the police will be standing around, and Sherlock will have put it there.. because it's his body. Although he may not be quite dead.[[/note]]
*** [[spoiler: And then there's the climax of "His Last Vow", where Sherlock shoots Magnussen in front of three police helicopters and Mycroft.]]
** [[spoiler: One of John's last lines to Sherlock in "The Reichenbach Fall" becomes this when you puzzle out who, exactly, is protecting whom.]]
-->'''Sherlock:''' Alone protects me\\
'''John:''' No. Friends protect people.
** Also, Mrs. Hudson's comment in "A Scandal in Belgravia", considering how [[spoiler:Moriarty finds out Sherlock's life story]]:
-->'''Mrs. Hudson:''' Family is all we have in the end, Mycroft Holmes.
** John's quote "The press will turn, Sherlock. They always turn, and they'll turn on you." from ''The Reichenbach Fall'' echoed eerily in the minds of some fans when they read [[http://www.thesun.co.uk/sol/homepage/showbiz/tv/4486222/Ben-Ill-posh-off.html some]] [[http://www.digitalspy.com/british-tv/s183/downton-abbey/news/a399632/benedict-cumberbatch-series-two-of-downton-was-fking-atrocious.html articles]] written about Benedict Cumberbatch, which used quotes that were no doubt taken completely out of context and twisted around. They media is definitely taking advantage of this self-proclaimed [[http://tvline.com/2012/06/14/sherlock-season-3-benedict-cumberbatch/ "PR disaster"]].
** The [[spoiler: cab driver's]] words to Sherlock: "I'm not gonna kill you, Mr. Holmes. I'm gonna talk to you, and then you're gonna kill yourself."
** The allusion to Jimmy Savile when discussing Moriarty's ''modus operandi'' as a criminal "Jim'll Fix It", in light of the 2012 [[PaedoHunt allegations]] about the late entertainer. [[spoiler: It doesn't help when we learn in "The Reichenbach Fall" that Moriarty moonlights as an award-winning children's storyteller]].
** The words "love is a far more vicious motivator" from "A Study in Pink" hurt much more since Sherlock [[spoiler:commited suicide to save the people he loves, his only friends]].
** All of these lines from "A Scandal in Belgravia" sound like wicked foreshadowing after watching "The Reichenbach Fall":
--> Sentiment is a chemical defect found [[spoiler:in the losing side]].
--> I've often thought that love was a [[spoiler:dangerous disadvantage]]. Thank you for the final proof.
--> This is your heart, and you should never let it rule your head.
*** They're just as painful in relation to "His Last Vow", knowing that Sherlock [[spoiler: kills Magnussen to protect John, and is almost sent on a suicide mission to Eastern Europe as punishment.]]
** Doubling as RealitySubtext, in "The Sign of Three", Major Reed's suspicion of John's motives for investigating the case, coupled with Sherlock breaking into the barracks and the (attempted) murder of Pvt. Bainbridge shorty after, leads him to immediately assume that they were responsible. After the 2013 [[http://en.wikipedia.org/wiki/Murder_of_Lee_Rigby murder of Pvt. Lee Rigby]], his paranoia about security come across as ''very'' justified.
* HeartwarmingInHindsight: A lot of Sherlock's behavior towards John in "A Study in Pink" seems like just common courtesy (thanking him for the phone, trying to turn him down gently when he thinks John is into him, waiting for him at the top of the stairs) until we reach later episodes, and we realize that Sherlock normally couldn't care less about common courtesy. The whole of season 3 also doubles as Tear Jerker in Hindsight.
* HesJustHiding: Sherlock is this in-universe, although in this case the speculators are correct. [[spoiler: As well as Moriarty for some, who expect JokerImmunity to be in play.]]
** [[spoiler: Indeed, Moriarty is seemingly alive at the end of "His Last Vow".]]
* HilariousInHindsight:
** Sherlock is being investigated by a reporter from ''The Sun'' and [[spoiler: finds a recording device planted in 221B]] at a point in the show's timeline (June 2012) that is four months after five ''Sun'' reporters and editors were arrested on hacking and bribery charges. Considering that particular episode was written and filmed several months before the ''News of the World'' scandal broke, it becomes either a FunnyAneurysmMoment and/or doubly hilarious.
** There's also the fact that ''The Sun'' was giving Creator/BenedictCumberbatch A LOT of attention around the time Series 2 aired in America. According to [[http://www.thesun.co.uk/sol/homepage/features/4302036/Sherlock-star-Benedict-Cumberbatch-is-voted-The-Suns-sexiest-man-beating-David-Beckham.html the polls]], brainy has indeed become the new sexy!
** The scandal regarding [[http://newsfeed.time.com/2012/08/22/prince-harry-naked-photos-surface-online/ Prince Harry's strip-poker shenanigans with female entertainers]] just practically screams the premise of ''A Scandal in Belgravia.'' Seeing a similar situation befall [[http://en.wikipedia.org/wiki/Catherine,_Duchess_of_Cambridge#Violations_of_privacy the Duchess of Cambridge]] after a few months makes it either [[HarsherInHindsight worse]]... or this.
*** Magnussen being an {{expy}} of Rupert Murdoch either makes this HarsherInHindsight or hilarious.
** Sherlock's line "Oh I may be on the side of angels, but don't think for one second that I'm one of them." Benedict Cumberbatch went on to play the Angel Islington on the BBC radio drama of Neil Gaiman's ''{{Neverwhere}}''.
** In 2012 episode "The Hounds of Baskerville," after Sherlock complains about experiencing emotions, Watson sarcastically calls him "Spock." In the 2013 film ''StarTrekIntoDarkness'', Benedict Cumberbatch plays [[spoiler: Khan Noonien Singh]], who has several showdowns with Spock.
** John's "Holy Mary!" reaction to Molly's dress in "A Scandal in Belgravia", when his wife as of series 3 is named "Mary".
** In "The Great Game" Sherlock goes "I am on fire!". A couple of years later, he literally [[Film/TheHobbit becomes fire]].
** In "A Scandal in Belgravia", [[Creator/BenedictCumberbatch Sherlock]] expresses distaste for [[Film/TheHobbit burglars]].
** The whole "Moriarty is an actor" scheme in "The Reichenbach Fall", since the release of ''Film/IronMan3'' and the backlash over Creator/BenKingsley's Mandarin being an actor.
** In "The Geek Interpreter", Melas mentions that he's talking to some of his mates in the comic book industry to set up a graphic novel series of their cases. [[http://robot6.comicbookresources.com/2012/09/bbcs-hit-sherlock-getting-a-manga-adaptation/ Guess what]] [[http://www.mangareader.net/sherlock happened]] later?
* HoYay: Has its own [[HoYay/{{Sherlock}} page]].
* {{HSQ}}:
** [[spoiler:The finale ending. Both seasons. THEY CANNOT LEAVE US LIKE THIS OH GOD.]]
** The ending to "A Scandal in Belgravia." [[spoiler: Irene's dead. No, she's alive. Irene's escaped. She's in love with Sherlock. She's dead without that information. Mycroft confims she's dead...and Sherlock's saved her. HSQ indeed.]]
** The ending to the ''[[{{Recap/SherlockS02E03TheReichenbachFall}} The Reichenbach Fall.]]'' Even when you know it's coming. Especially when you know it's coming. [[spoiler: John saw Sherlock fall. He touched his body. How on ''earth'' do they come back from that? Possible answer: It helps attempting to fake a death when you have a forensic pathologist who do nearly anything for you.]]
** The entire show, really.
** Season 3's finale is probably the greatest one yet. [[spoiler: Sherlock leaves by plane after murdering Charles Magnussen, the villain of the season. Cue a fake-out cut to the "credits". But wait! A threatening message spreads through the country! Who could it be for? Who's it from? ''It's from [[BackFromTheDead Moriarty.]]'' ]]
* HypocriticalFandom: CBS' ''Elementary'', as announced in January 2012, is a modern day retelling of Sherlock Holmes, except in New York. While there is concern the basic idea is a ripoff of ''Sherlock'', the fanbase has been livid, asking why Americans can't make anything original. Which is ironic, because the very premise of ''Sherlock'' is derivative. The books are probably some of the most influential fictional works of the nineteenth century, which have been adapted into or inspired [[RecycledInSpace in whole or in part countless other works]], including several successful TV series. ''Sherlock'''s main virtue in that regard is that it stayed in England when it modernized, and is based directly on the Doyle canon, instead of just the basic premise with serial numbers filed off.
** The main issue seems to be that ''Elementary'' [[http://www.independent.co.uk/arts-entertainment/tv/news/legal-thriller-looms-as-sherlock-takes-his-caseload-to-new-york-6292682.html apparently]] is based off of an American remake of ''Sherlock'' that the BBC rejected permission for, hence some of the cause for concern that it will be a knockoff of ''Sherlock'' and not a new adaptation of the books.
* IdiotPlot: Moriarty's plan in ''The Reichenbach Fall'' relies on the police becoming suspicious of Sherlock for a weak reason and Sherlock reacting by acting ''very'' suspicious, and it works. However, this ''is'' Moriarty -- he likely had contingency plans and leverage on relevant parties ready to make it work one way or the other. [[spoiler:We also find out in the third series that Sherlock was deliberately playing to Moriarity's plan so that his own and Mycroft's plan to take Moriarity down would work.]]
* JustHereForGodzilla: Admit it, you only first bought the tie-in editions of ''Literature/TheHoundOfTheBaskervilles'' and ''Literature/TheSignOfTheFour'' for Benedict Cumberbatch's/Martin Freeman's introduction.
* LikeYouWouldReallyDoIt: [[spoiler:Sherlock is quickly revealed at the end of the second season to not have died, but to have somehow faked his suicide.]]
* LoveToHate: Moriarty, whose '''''deliciously''''' evil personality has him competing with [[Film/TheDarkKnight The Joker]] and [[Manga/{{Monster}} Johan]] for the title of: "Most [[MagnificentBastard Magnificent]] of all [[CompleteMonster Monsters]]"
* MagnificentBastard:
** Moriarty, ''Big Time''. He's the mastermind behind all cases Sherlock goes into throughout the series, manages to avoid capture, and personally runs into Sherlock twice without getting captured. ''Fooling him with a disguise'' the first time.
*** He takes it even further in ''The Reichenbach Fall'', turning everyone, up to and including '''''both Holmes brothers''''' into {{Unwitting Pawn}}s as part of his sadistic plan to absolutely ''destroy'' Sherlock. And no matter how far he skips over the MoralEventHorizon one cannot help but applaud (albeit while hiding under the bedsheets).
*** Four words: [[spoiler: [[HesBack "Did you miss me?"]]]]
** Sherlock is a rare heroic example.
** Similarly, Irene Adler TookALevelInBadass from her FauxActionGirl status in the books, to a full on example of {{The Chessmaster}}.
** Mycroft, who not only ''is'' the British government, but can [[spoiler:fake plane crashes]] and order assassinations.
** Charles Augustus Magnussen runs the entire Western world from one room in his house where he stores the privates information of celebrities and world leaders. [[spoiler: The room is just for meditation- in fact he stores all that information ''in his mind''.]]
* MemeticBadass: Both Mycroft and his Umbrella.
** Molly Hooper dated the most dangerous man in Britain. Then dumped his ass.
*** After turning him into a [[{{Series/Glee}} Gleek]].
** According to the Internet, John "[[MemeticSexGod Three Continents]]" Watson is a tiny assassin in a cuddly jumper.
* MemeticMutation:
** In "The Reichenbach Fall", there is a short scene in which Donovan rushes into Lestrade's office to tell him that there's been a break-in. Lestrade, who has his feet up on the desk and is eating a doughnut, simply replies "Not our division." The fandom went nuts with the line.
** According to LiveJournal, John's mustache has more important things to do than be on John's face, like [[MemeticBadass taking down terrorist cells and winning the Olympics.]]
** Also, [[ButtMonkey Anderson]] has a, shall we say, ''deep'' interest in dinosaurs.
** Mycroft is sending you secret messages through the Captcha.
** [[HarkAVagrant John apparently REALLY likes jam.]]
*** Especially strawberry. Which is odd and a bit disturbing, since the only mention of strawberry jam in the series is in the context of someone being ''struck by a train''.
** Three words: [[http://sexuallyoblivioussherlock.tumblr.com/ Sexually Oblivious Sherlock]].
** After the series 2 finale, [[spoiler:"[[Film/TheDarkKnight I believe in Sherlock Holmes]]" and "[[http://earlfoolish.tumblr.com/post/15969467726 Moriarty was real]]".]]
** ''JAWN!''
** John is a... hedgehog, apparently. And Sherlock is a cat. Or an otter.
*** The otter is especially common. It's called "Otterlock"
*** These just keep coming. Now, [[http://24.media.tumblr.com/tumblr_m1oz1lprMg1qm3wmuo1_500.jpg Moriarty is a lizard,]] and [[http://25.media.tumblr.com/tumblr_m1mq11LABj1roowpfo6_r1_500.png Mycroft is an owl.]] Doyle himself described Lestrade as [[http://freemanisahedgehog.tumblr.com/post/22858462417/tealbluestatic-thenakedsociopath-my-god ferret-like,]] so we really only need Irene, Mrs. Hudson, and Molly to round out the set.
** "''I will burn you.''"
*** "-[[LastSecondWordSwap a CD of my favourite songs.]]"
** [[http://www.tumblr.com/tagged/pressed+sherlock+fandom Pressed Sherlock Fandom]] is gaining popularity among Sherlock fans who support Elementary. [[http://onlyforthepressed.tumblr.com/ It even inspired an entire blog.]]
** Referring to a fanon AlternateUniverse of the show as (NAME)-lock. The most popular being: Kidlock [[SpinOffBabies (Sherlock and John as children)]], Parentlock [[KidFic (Sherlock and John raising a child)]], and [[{{Rule63}} Femlock]].
** [[http://littlemisshamish.tumblr.com/tagged/really-high-john Really high John]].
** [[http://grace-and-dignity.tumblr.com/post/67931283522/things-that-happened-before-sherlock-series-3 "Even X came back before Sherlock]]", a reference to how other fandoms get a ton of new material during the show's extremely long hiatuses.
*** The real world as well. ''Britain got its [[http://en.wikipedia.org/wiki/Andy_Murray first male Wimbledon champion in seventy-seven years]]'' before we got more ''Sherlock''.
** John, I mustache your a question. Watson your face?
** "WELL I'M NOT ''NOW''!!!"
** [[Film/TheHobbit Bilbo and Smaug high as fuck, solving crimes and shit]].
* Moe: The fandom accepts Molly Hooper and John Watson as some of the cutest characters in the show, the latter for his cuddly jumper.
* MoralEventHorizon: [[spoiler:Moriarty strapping one of his bombs onto a ''little boy'' and forcing him to count down to his own demise.]] Everything he did in that episode was horrifying, but that moment reveals just how sick a bastard our heroes are dealing with.
** In "His Last Vow", Magnussen crosses it by [[spoiler:threatening Mary Morstan with blackmail, that would doubtlessly be catastrophic for the Watsons]]. How bad is this? It's so bad that Sherlock [[spoiler:outright ''murders'' him, something that he didn't even come close to doing with Moriarty]]. This is assuming he didn't cross it by driving a man to suicide or trying to burn [[spoiler:John Watson]] alive
* {{Narm}}[=/=]NarmCharm: For some, virtually every word out of Moriarty's mouth in ''The Great Game'' and ''A Scandal in Belgravia''. (He seems to have graduated from Cesar Romero to Heath Ledger since.)
** Two glorious examples in "His Last Vow": First is Sherlock [[spoiler:dramatically crawling up the stairs back to his mind palace complete with infinitely swelling music]], second is [[spoiler: Magnussen enjoying himself just a little too much while going through the files in his own mind palace]].
* NarrowedItDownToTheGuyIRecognise[=/=]NotSoSmallRole: Some viewers saw the identity of Moriarty coming due to this trope.
* OlderThanTheyThink: When the series was first announced, there was some minor purist outrage at the very idea of taking Sherlock Holmes out of his Victorian milieu and into the modern day. Both Moffat and Gatiss pointed out that the Basil Rathbone movies, among others, had adapted Holmes' stories to a contemporary setting as well.
* ParanoiaFuel: Have ''you'' ever taken conventional wisdom as a given, because you heard it in the news or read it in a history book?
* RescuedFromTheScrappyHeap: Anderson is now very much liked by most fans after "Many Happy Returns." Most surprisingly, though, ''Kitty Riley'' of all people is getting this, as more fans are slowly becoming sympathetic to her after they learned how Moriarty had used her.
* RonTheDeathEater: Donovan and Anderson have been hit HARD by this in the aftermath of ''Reichenbach''. It frequently gets uncomfortably sexist in Donovan's case (witness the EditWar over her page on the fan-wiki). Though Anderson seems to have redeemed himself with his Atoner personality in Season 3. Irene gets this too.
* TheScrappy: Naturally, [[JerkAss Sergeant Sally Donovan]] is universally disliked by the fanbase, if not outright ''hated.'' Kitty Riley also counts as well.
* ShipsThatPassInTheNight: Mycroft/Lestrade is surprisingly popular considering they have ''never'' been in a scene together.
** Although considering Mycroft ''is'' Big Brother (both literally and figuratively), since Lestrade is on the police force, and both are closely tied to Sherlock Holmes, it's not a far reach to assume they do know each other. Besides, when has something like that slowed down fans? After "Baskerville", when it's implied that ''Mycroft'' sent Lestrade to Dartmoor to check up on John and Sherlock, the ship has gained even more steam.
** Barring that, they might have simply paired them together ''because'' they don't share any screen time, as a way to create something new without interfering with the shows already delicate and convoluted web of shipping. Basically a long-term FanficMagnet.
** Sherlock/Molly, and Sherlock/Moriarty gained massive popularity in the fandom after the Season 3 Premiere
* ShipToShipCombat: Involving a straight man, a gay woman and a potentially asexual virgin MarriedToTheJob. Now ''that'' is talent.
** As Sherlock/Molly has become more popular after Series Two, it has had its own run-ins with Sherlock/John fans. Surprisingly, Sherlock/Molly shippers get along fairly well with Sherlock/Irene shippers.
** The Johnlock shippers have their own wars with the John/Mary and the John/Mary/Sherlock shippers after season 3.
* SoOkayItsAverage: The unaired {{Pilot}}. Definitely a great crime drama with the same quality of acting and direction, but probably didn't have the epic, high-budget treatment the final product deserved, and might not have satisfied [[{{HypeBacklash}} the incredibly high expectations some might have for such a famous property]]. Also, no [[{{EnsembleDarkhorse}} Mycroft]].
* SpecialEffectFailure: A number of examples.
** In ''The Blind Banker'', the villain fires a gun repeatedly in a museum. There's no sound of bullet impacts, and nothing at all gets hit, even when he's firing directly towards Sherlock while he's surrounded by glass cases. While it's not beyond the realm of possibility the bullets missed -everything- that would have broken visibly, it does strain belief and indicate they were probably running around in the real museum just after hours and couldn't move anything around to set up prop cases.
*** Actually, in the draft of the script, there was a line indicating that the bullets were in fact blanks. The line was removed in the final version, but the possibility remains.
** In "A Study in Pink", in a scene while Sherlock is in the foreground in the police station, the room around him goes dark to increase the contrast of the graphic effects playing out showing Sherlock's thought processes while dissecting a clue. When he's finished ''(twice!)'', the graphics go away and the room lights up again. But rather than having darkened the scene in post-production, they had literally turned the lights off in the room, so when they come on again, a dozen ceiling florescent bulbs flicker madly to life.
** In "His Last Vow", after [[spoiler:being shot]], Sherlock falls backwards in stylistic slow motion as the room tilts along with him. While otherwise being very well done, in the background, a large flower vase begins to slide across the floor as the room tilts out from under it.
* {{Squick}} The entire sequence between Magnussen and Elizabeth Smallwood. He touches her hand, fights her attempts to break away and describes [[spoiler: the underage girl her husband exchanged elicit letters with]] as "delicious," "yummy" and "yum yum." He even [[spoiler: ''licks her face.'']]
* TakeThatScrappy: In the faux news report of Sherlock's return released shortly after season 3, Kitty not only admits she was wrong, but then apologizes and [[PanderingToTheBase talks at length about how stupid she was]].
* TheyChangedItNowItSucks: Some die-hard fans of the original novels dislike the characterizations which have been given to Sherlock, Mycroft, and/or John.
%%* UnfortunateImplications:
%%** Every speaking Chinese character in the second episode is one or more of the following: an assassin, a circus artist, a gang member or a smuggler. Except for Soo Lin, who's only a ''former'' smuggler. And she ends up dead. In fact every ethnicity shown is a stereotype, as the episode opens with Sherlock fighting a living embodiment of an Arabian stereotype, complete with curved sword. A similar stereotype shows up in Belgravia - modern day terrorists so stereotypical that they execute their prisoners with swords.
%%*** This is a textbook example of a {{Setting Update}} not quite going far enough. This story might have flown at the time the original stories were written, but certainly not now.
%%*** Though to be fair, most characters which turn up in the show are either criminals or victims, and if you really pay attention, there are a lot of different ethnicities sneaked into the cast in minor roles. For example Corporal Lyons from The Hound of Baskerville seems to be of Asian descend. And The Blind Banker features with Soo Lin's boss at least one an entirely non-stereotypical ethnic person in a position of authority. Plus, The Blind Banker is actually the only episode which features non-European criminals in the whole series.
%%** Moriarty being changed from English to Irish might count (though to be fair Moriarty ''is'' very much an Irish name so the subtext might have been there all along.)
%%** Irene Adler labels herself as "gay", has LesYay with her bodyguard, but it is her feelings for Sherlock that are ultimately presented as the most genuine. On one hand, she is [[spoiler: reduced to a helpless pawn by Mycroft and must be saved by Sherlock from ''getting her head chopped off''. On the other hand, while Sherlock may have bested her in the end, she still managed to beat him twice. That's more than most of his adversaries can say. Also, he apparently had difficulty realizing his interest in her was more than intellectual.]]
%%*** It's worth taking note that before she even met Sherlock, Irene has had affairs with ''both'' parties of a married couple.
%%*** They could have avoided part of this by just having her identify as bisexual, but NoBisexuals right?
%%** As referenced in the Irene entry above, what reason was there to introduce [[spoiler: presumably-Islamic extremists who nearly chop off Irene's head]]? An assassination attempt could have been depicted any number of ways that were less... that.
%%** Some [[PeripheryDemographic older fans]] who aren't as into Creator/MarkGatiss or the HoYayShipping aspect find the portrayal of [[CampGay Moriarty]] [[AmbiguouslyGay homophobic]], although it could be argued that mostly-good guy [[MagnificentBastard Mycroft]] [[CampGay cancels]] [[CampStraight it out]]. There is also the gay caricatures that made up one of Morarty's puzzles.
%%** A good amount of people could help but think it was a little messed up that Irene [[spoiler: walks in naked on Sherlock to make him uncomfortable, and not in the aroused AllMenArePerverts way,]] drugs and attacks him (although the attack wasn't particularly life threatening), a very mild form of DoubleStandardRapeFemaleOnMale. But then there's the fact that after Sherlock [[spoiler: went loopy from the drugs and unconscious, Lestrade and others filmed him because they thought it was funny. Completely ignoring the fact that they had no idea what she gave him and it could have had serious ramifications]] This is all PlayedForLaughs, basically. [[DudeNotFunny This would be VERY different if the genders were reversed.]]
* TheWoobie: Molly. Part of the reason why Watson, Lestrade and Mrs Hudson are so kind to her because they clearly recognise that absolutely nothing ever works out for her. ''Nothing''.
** Let's focus on ''Scandal'' in the morgue. When Sherlock tells her she didn't have to come in, she says "It's all right, everyone else was busy with Christmas." Apparently, the girl is completely alone as well, which just makes her clinging to Sherlock all the more gut-wrenching.
** Plus, [[http://www.mollyhooper.co.uk/blog/01april her blog]] which she documents her falling in love with Sherlock to falling in love with Jim to [[spoiler: finding out that Jim is Moriarty]]. Unlike the other characters' blogs, this one ranges into TearJerker territory. A fan asked Moffat if anything was going to go right in her life. All he got was a vague "Well…", implying that her Woobie status isn't going anywhere for a while.
** Molly falls into this so hard that [[spoiler:even ''Sherlock'' feels bad for her, after he humiliates her over a present he deduced she meant to give to a boyfriend only to find out that it was her present for him. She tells Sherlock, in the most heartbreaking way possible, that he only ever says nasty things to her. Sherlock just looks horrified, before apologizing and kissing her on the cheek. This is from a guy who describes himself as a "high-functioning sociopath".]]
** Henry. His mother died when he was very young, then ''he watched his father DIE'' [[spoiler: by the hands of Dr. Franklin, but he was manipulated into thinking it was a monsterous Hound]], becoming an orphan from the age of seven, which left HUGE mental scars on him, so much so that everybody takes him as mentally disturbed. And he apparently doesn't have much of a lovelife or any nearby relatives. And what's worse is [[spoiler: Dr. Franklin is STILL DOING IT TO HIM until Sherlock and Watson solve the case, and Henry almost commits ''suicide'' over it. It's amazing he even survived the episode.]]. Poor guy...
** JerkassWoobie: Sherlock, occasionally. He is a self-proclaimed "[[SociopathicHero high functioning sociopath]]" who generally acts like a dick and solves crime for fun, not justice. [[ManipulativeBastard He is also very manipulative]]. But Sherlock is redeemed by his PetTheDog moments, as well as his lapses into vulnerability, so it's hard not to feel sympathy for him. He slides slightly further towards the Woobie end of things in Series 3, owing to having TookALevelInKindness.
** StoicWoobie: Major Sholto, and how!
