While the Doctor has gone through many adventures in time and space, being [[LongRunner the longest running Science-Fiction show ever created]] means that there's bound to be [[DarthWiki/DethroningMomentOfSuck some moments]] that people want erased from history.

[[folder: Classic Series ]]

* @/{{Metz77}}: Peri in general is a dethroning character, but her absolute worst moment is in her debut episode, "Planet of Fire", when Nicola Bryant, struggling to make her American accent sound even '' slightly'' convincing, attempts to be defiant at the Master with the line "I'm Perpugilliam Brown and I can shout just as loud as you can." Instead of sounding defiant and confident, it comes out shakier than a bobblehead in an earthquake.
* @/{{Sceptre}}: "The Twin Dilemma". Strangling the companion is not the best way to present a new Doctor to the world. It pretty much killed the show for twenty years. And the plot is so bad the novelization is a thousand times better, in a world where the reverse tends to happen.

[[/folder]]

[[folder: New Series ]]

* @/{{Ecclytennysmithylove}}: I sometimes tolerate New Series episodes that other fans have negative views on (specifically “Love and Monsters” and “Fear Her”, those two episodes that I don’t really find that bad). But if I can think of one episode that nearly stopped me from watching the New Series, it would be “Father’s Day”. I know what the episode writer, Paul Cornell (his written two-parter, “Human Nature” and “The Family of Blood”, were actually great), was trying to expand the rules of the space-time continuum (i.e. Reapers), but still, [[CanonDiscontinuity none of the established rules ever came back after that episode.]] What even pissed me the most was the [[JerkAss Ninth Doctor calling Rose a 'stupid ape' for saving her father from the accident,]] [[FreudianExcuse even though she did it because she wanted to get to know her father]]. I'm sorry, but as a victim of emotional abuse, that nearly made me lost my sympathy for the Ninth Doctor when [[spoiler: he regenerated]]!
** @/{{TylerFG}}: My sympathy for Nine was completely destroyed when he told the Dalek in its titular episode to go kill itself. Whether the Dalek had it coming or not, you never tell somebody to kill themselves, and I was expecting so much better from somebody as open minded as the Doctor! And he's supposed to be the hero of this show? Even if Rose told him off near the end, that still doesn't excuse his disgusting actions in that episode.
* @/GentlemensDame883: At the risk of earning the ire of Nine fans, I found his chickening out of destroying both the Daleks and Earth in "Parting of the Ways", given his previously established Badassitude in taking Van Statten's gun to use against the Dalek and not flinching from Margaret Blaine's attempted shaming of Team TARDIS in "Boom Town", to be one of these.
* @/{{Rushi}}: "The Christmas Invasion". If Harriet Jones is supposed to bring a Golden Age to Britain, I believe that Ten should have let her do it. Or the Reapers should have shown up and screw him and Rose over for messing up the timeline or something.
* [=InTheGallbladder=]: I think I'll step up to the plate and add "Love And Monsters" to the list. Lazy writing, lots of padding, shoddy humor and a mountain of stupidity all steadily accumulated over the course of the episode, to the point where they were practically unignorable. But the fun doesn't truly begin until the villain is revealed to be a complete ripoff of [[AustinPowers Fat Bastard]], to the point of even having a similar-sounding accent. It's at this point that Ursula is reduced to a disembodied face that protrudes out of things. She's then robbed of her dignity, leading into the reveal that she will spend eternity a talking paving slab. [[EsotericHappyEnding This is considered a happy ending.]]
** Jarxon6: That was all minor, to me at least, compared to the EPIC derailing of both Rose and the Doctor. There's this big monster, threatening to absorb someone, several innocents trapped in an AndIMustScream situation, and the doctor has a more or less instant solution. So, what does the Doctor do? Stands back and watches Rose bitch out the guy for a fairly minor thing, thus making it impossible to free the people trapped. Let me repeat this: our heroes condemn innocent people to AFateWorseThanDeath so Rose can complain.
* @/romanatorX: Almost everything about "Fear Her" was an embarrassment to the series, from the bad acting to the idiot balls. I would nominate the childish aesop about "Love conquers all" to be the episode's nadir, but no. The ultimate low point for the entire franchise is the drawing of Chloe's abusive dad being turned back to life. So how do they defeat him? Chloe and her mother... sing him away. Yes, you heard that right. They sing a living being away. That is so childish that it is actually insulting to the millions of fans who practically begged the BBC to bring back ''Series/DoctorWho'' for so many years. And even if it wasn't prodding to the youngest demographic, you could tell that the writers, when coming up for an ending to this episode, [[TheyJustDidntCare threw their hands up in the air and said "We don't give a damn!"]] Give me the charm (mediocre special effects, SoBadItsGood acting) of the old series over this childish excuse of a ''Series/DoctorWho'' episode any day.
* NCZ: "Last of the Time Lords". When all hope is lost and the heroes (and writer) have been backed into an inescapable corner, [[TastesLikeDiabetes Martha gets everyone in the world to say the word, "Doctor" at the exact same time,]] which transforms The Doctor into Jesus and allows him to defeat The Master. It's ludicrously cheesy and a DeusExMachina at its finest. And to top it all off, we get a ResetButton ending, and The Master comes back anyway.
** Calamity2007: Also the reveal that the Toclafane are [[spoiler: the future of humanity, who in an effort to escape the death of the universe, turned themselves into cyborg creatures, with minds of children, that cannibalize and kill each other for fun]]. That's right, in one simple reveal, RTD managed to make any optimistic speech about the human race moot, since apparently [[spoiler: we are all doomed to become psychopathic man-children no matter what]]. Just feels like the only reason the plot twist was even included was to just make The Master look more evil for using them.
* Tropers/{{Larkmarn}}: As much as I disliked Donna (... which is a lot, by the way) the titular girl in "The Doctor's Daughter". Now, not only do I take issue with introducing an item that can single-handedly allow the Doctor to recreate the Time Lord race (granted he has gone back and forth on whether or not that would be a good thing or not, but it's still worrisome), but then functions as a massive CanonSue, being birthed fully formed with Time Lord intelligence and ActionGirl abilities. But the absolute dethroning moment was the end. Despite being, you know, dead, she regenerated... but for some reason, she kept her body and instantly went on an AndTheAdventureContinues.
* @/{{Renita}}: ''Series/DoctorWho'' episode "Journey's End". So, many reasons, including the regeneration tease, the Clone Doctor, the Doctor's reaction to the Clone Doctor's rational decision to kill the Daleks when they were clearly beyond redemption, the Doctor fobbing Rose off with the Clone Doctor, Donna defeating the Daleks with Time Lord leet haxxor skillz, Donna being given a psychic lobotomy, the Earth being towed back whilst that "you should feel moved now" music plays in the background like a cue card and Davros being downgraded from MagnificentBastard to a Dalek pet just to sate the wrath of the FanDumb that objected to him ever overshadowing his creations despite being far more interesting than they are.
** @/{{Loquacia}}: The realization of the complete bollocks that the Daleks would keep a "blow us up" button in the first place rather spoiled the episode, let alone that they'd keep it in the same room as their enemies.
*** @/{{cavenglok}}: Well, it's not really a blow-up button... The Doctor says he's maximizing Dalekanium power feeds, which probably means that the power feeds were meant to be useful, like to provide more energy for their armor or something. Still pretty stupid that they'd keep it in the same room as the Doctor, though...
* @/{{Crazyrabbits}}: The "dramatic" gun scene in "The End Of Time, Pt 2". Was there really any doubt that The Doctor was going to shoot the computer maintaining the link? Not to mention that [[spoiler: the other supposed targets in question could both regenerate and shoot lightning bolts from their hands]]. It even underscores the power of the next scene, where [[spoiler:a pissed-off Master unloads all the electricity he has into Rassilon, driving him back into the gateway]].
** @/{{polooglu}}: Ten saying "I don't want to go". Sure, tons of people think it's sad, but really considering the Doctor has done it nine times prior, and never complained as much, and got to wrap up all his loose ends (something I would be grateful to have done before I died), the fact that he still goes into his regeneration kicking and screaming just leaves a bad taste in my mouth.
*** @/{{Sonikkuruzu}}: Ten also seemed to be holding on for as long as possible, almost as if he wanted his next self to be born in a crashing TARDIS. Partly sad though mostly selfish.
*** @/{{Hyrin}}: I wasn't so bothered by Ten saying goodbye as I was by the fact that his regeneration somehow flipped the SelfDestructMechanism on the TARDIS. Several Doctors have regenerated inside the TARDIS without sending it out of control towards the nearest inhabited area, and it just felt like a cheap setup for Eleven to be the wacky one who laughs as his flaming ship plows towards some hapless Scottish garden.
* @/{{LahmacunKebab}}: "Day of the Moon". Wait, so genetically engineered priests from the future have been secretly controlling humanity since prehistory just because they wanted space suits? Needlessly complicated doesn't even begin to cover it.
* @/{{nostalgicfan}}: "The Doctor, the Widow and the Wardrobe". The underlying Christmas message quoted: "Men are weak". I have forgiven almost everything in Doctor Who, but I cannot forgive this episode. The plot holes are just huge and would take an entire page to fill, but I'll take one: The Doctor, a neigh immortal Time Lord, with memories of over ten lifetimes (which, when the Flesh tried to emulate, it was completely overwhelmed by without the Doctor keeping it together), was an unsuitable carrier for the [[OurSoulsAreDifferent Tree Lights]] because of his male organs. Fortunately, there was a woman around, so she could fly the tree-ship through the Time Vortex. No kudos was given to the young boy who had led them there (and come on, would any kid 'really' do that if they found a magic portal?). The message was vindicated as much as possible by the plot by having all the male characters act like gung-ho idiots, with only the women being the sensible ones. I just want to forget this episode ever existed, and I genuinely feel sorry for any young boy who watched this one.
* James Picard: "Asylum of the Daleks". The entire episode relied on viewers eating up incredibly dumb stuff. The Daleks characterization is completely ignored, the much-hyped "Classic Daleks" only get cameos; the Amy and Rory divorce was stupid, offensive, and to finally twist the knife in the wound, it was filler! [[BigLippedAlligatorMoment It never came up again!]] Then there was the fact that even Oswin's voice was inconsistent, and really, it was just a horrible episode that needed either major rewrites, or just plain trashing. This was Moffat's lowest point for me.
** pulsor93: Slightly subverted by "The Snowmen", [[spoiler: which featured Clara Oswin Oswald.]] So much for it being filler.
*** Telepresent: The episode wasn't filler, but the whole divorce business certainly was...
** @/Dragonmouth: The big reveal of why Amy and Rory are getting a divorce. Amy says she left Rory because [[spoiler: she could no longer bear children after her experience at Demons Run and felt she was no longer worthy of him]]. First of all, Rory never showed any particularly strong interest in raising children. But what really makes this a Dethroning Moment is how horrifically it derailed Amy's character. I can understand why Amy might be angry at the Silence for what they did to her but I cannot see her being ashamed of her [[spoiler:inability to have children]]. She should have had an honest discussion about [[spoiler:her infertility]] with her husband but instead she ran away from him without telling him why, which is irrational and cruel. Amy was a smart, spirited, loving and mature woman, but now she seems to believe that a woman is worthless to her husband if she is [[spoiler:unable to bear children]].
* Kellor: "The Power of Three". As others have summed it up, it's like the writer came up with an interesting idea, wrote himself into a corner, and came up with a nonsense ending just to be done with it. We've got an alien race that the Time Lords apparently believed were just a myth (which seems like a phrase we've heard so much that's its become cliche). They want to stop humanity from colonizing space. This is a cool motivation that is just wasted on this episode- there's no sympathetic or even relatable face put on the Shakri, they're just another race of jerks. We don't even meet a real one, just a soapboxing hologram. They're advanced enough that they can time travel, build indestructible and scientifically inscrutable devices, and can hide in parallel dimensions. Yet the best plan they could come up with took a year to execute and only killed a third of humanity. Only the aliens from ''Plan 9'' were less competent. Had the cubes used biological, chemical, or even conventional weapons, Earth would have been screwed. One of the cubes sprouted a gun and flew around shooting- why didn't they all do that? And why did they need to study humanity for 47 minutes if they came from a future that was overrun by humans? Why did one of the cubes play the Chicken Dance? Why was the robot girl with the weird eyes sitting in that hospital all year? Why were the aliens (androids?) with the weird mouths kidnapping people from the hospital? Nothing made sense. Added to that, we've got Brian sitting in the Tardis watching a cube for two days straight without moving or anyone noticing (remember when Mickey was justifiably miffed about holding a lever in the Tardis for an hour?), we've got the Doctor being a real pain in the ass about sitting still for a few minutes, and we've got all of humanity bringing unknown alien things into their homes and businesses because humanity is just quirky like that. This didn't have characters playing with an IdiotBall, it had everyone playing in an Idiot Ball pit.
** Valjean: The main redeeming factor to this plot was that no one really cared about its stupidity because it was pretty much a minor ExcusePlot for the Doctor to hang around on Earth with Amy and Rory, and the character-driven real plot of the episode was Amy and Rory adjusting to and settling into their non-world-saving normal routine of daily life and responsibility (because they did it while saving the world, but saving the world from a slow invasion that was taking months to get underway -- it crept up on them very naturally), realizing that they love the Doctor but can live without him, the Doctor being regular friends with Amy and Rory and slowly letting them go, and it all seemed to be moving towards a logical ending of them having one last crazy adventure before amicably retiring from companioning for good in a satisfying and optimistic manner. Then we got "The Angels Take Manhattan" instead. *thud thud thud*
** {{Tropers/PentiumMMX2}}: This episode was easily my least favorite of the revived series, entirely because the main plot felt like a waste. To me, it actually had good build-up, and given how there was maybe 5 minutes left on the episode when the villain revealed what their plan was, I expected it to be a two-part episode. But, they resolve the plot by having the Doctor use the sonic screwdriver on one of the control panels for the alien ship, causing it to self-destruct and somehow resurrect everyone who died as a result of the cubes. I was very much annoyed by this; it felt like they wanted to make this a two-part episode, but were unable to, so they just hastily cobbled together an ending.
* @/DarkHero9: "The Angels Take Manhattan", just all of it. But if you want a more specific reason for why this episode is the lowest point in the Moffat era, we'll begin with the ridiculousness of the plot that relies on a paradox that makes absolutely no sense after you think about it. A new rule that comes right out of nowhere that subverts the "Time can be rewritten" message that had existed throughout. Not only that, but Amy and Rory's departure is the worst companion departure ever on this show, simply because of how mean-spirited it is, as well as rendering the bulk of the plot of the episode completely pointless. It's the worst case of TheBadGuyWins that I have ever seen in any media. Especially since, in all honesty, their stories ended just fine in Series 6; there was absolutely no reason to do this episode other than because Moffat apparently disagreed. Not only that, but it doesn't match the tone of the rest of Series 7, especially where Amy and Rory's story was going. This episode sucks and deserves to be forgotten, it's such an absolute waste of two awesome characters in the worst way imaginable.
** @/DynamiteXI: This. The Amy arc should have ended with Amy accepting that she doesn't need to wait anymore, telling the Doctor that he can move on, but the episode forces the decision on her and only serves to give the Doctor angst. Plus, Moff seems to be sticking to the dogma of "fixed points in time," even though the Doctor actually HAS looked ahead to a BadFuture and still managed to change it (at least [[Recap/DoctorWhoTVMTheTVMovie twice]], [[Recap/DoctorWhoS32E10TheGirlWhoWaited anyway]]). It's like the showrunners are trying to one-up each other with tragic ways to permanently dismiss companions. Except this time it felt exactly like when Peri was killed off in the classic series, yet got some kind of tacked-on EsotericHappyEnding. Anyway, this episode certainly killed Season 7's good vibes.
** @/{{Highwind}} - "The Power of Three" would have been a superior ending to Amy and Rory, especially since the whole episode was about them finally settling down in a post-Doctor life. They could have simply said "No, you go on your own" to The Doctor, Doc could have been sad for a while, and then gotten the new companion. Instead, we get this abomination, which butchers Angel rules again (Angels are clearly moving and existing while being looked at, or with camera focus on them. The fact they didn't move even when you were looking at them was part of the creepiness), has several paradoxes, and as others have mentioned goes against Amy and Rory's plot arc as a whole.
** @/{{Sedirex}}: And seriously, the Statue of goddamned Liberty? You really expect us to believe no one in all of Manhattan looked at it in the entire time it was taking a stroll?
* @/{{MrThorfan64}}: "Journey To The Center Of The Tardis". The ending felt like the God of Lazy Writing (the Doctor) stepped out of a machine (the crack in time in the TARDIS) and solved the problem. I feel this episode was a missed opportunity, the zombies could have been something the Doctor was keeping in the TARDIS for unclear reasons, emphasizing his mystery. Instead we got such a poor explanation. And unlike The Girl who Waited they didn't touch on the fact that a new timeline would effectively destroy their future versions. Such a disappointment when I had such high hopes.
* @/NovusWulf: "Nightmare in Silver". The episode shows signs of running out of ideas when the whole Imperium is unashamedly ripped straight from Warhammer 40,000 - "Punisment Platoon" being a nice rewording of Penal Squad, the soldiers clearly dressed like classic Cadians and armed with Lasguns, and they even have a goddamned Emperor (who mercifully is NOT a corpse on a Golden Throne, thank god)! However, where I really take umbridge with this episode is what it did to the Cybermen. It's something Moffat and team have been doing for a while now - first the Daleks being changed from a Nazi Allegory to "they take love and replace it with hate" or some other BS, but now they've turned the Cybermen into a carbon copy of the Borg! Weren't the Borg Cybermen ripoffs? At any rate, the sheer amount of Plagiarism going on and the absolutely awful re-imaging of the Cybermen makes this episode my new low point. Oh, and those insufferable, terribly acting kids (who were to some credit at least out of the way for most of the running time). Good god, Moffat and friends, was this awful.
* fluffything: I'll just flat-out say it. I did not like "The Name Of The Doctor". I felt it was overhyped, had an uninteresting villain (sorry, but The Great Intelligence does not deserve to be among the likes of The Master and/or Davros as an arch-nemesis for The Doctor), and ended on a predictable cliffhanger (Though, I will admit I do like the idea of Creator/JohnHurt as an alternate Doctor). But, my biggest problem is the reveal of who or what Clara is. How she is able to exist in many different timelines at once. The reveal? [[spoiler: It is due to her entering The Doctor's time-stream (IE: his life) in order to save him from the GI causing her life to split into over a million different versions]]. That's right, the whole thing was one big [[BecauseDestinySaysSo "Clara is destined to save The Doctor!"]] reveal. Or, to put it bluntly, they turned Clara into one big MarySue. What should've been a huge reveal for The Doctor is turned yet into another "Clara-centered" episode as she once again steals the spotlight. They could've had River, Strax, Jenny, and Vastra all joining Clara as she [[spoiler: enters The Doctor's time-stream to save him from the GI]] in a big epic moment of "Let's save The Doctor". But, nope, instead, we have to have Clara be miss PuritySue and sacrifice herself to save The Doctor all by herself because otherwise we couldn't reveal that this is how she exists in multiple time streams. What a load of bull. Give me back [[FanNickname "Dalek Oswin".]] At least she was more interesting and compelling of a character than little miss MarySue here.
* @/{{ThatRandomGuy42}}: I'm not angry over "The Time of the Doctor", but it was rather disappointing in many aspects. The massive war on Trenzalore didn't look like much of a war until near the end, there were one too many things to keep track off (especially with the TimeSkip mechanic thrown in) and the solution to the Doctor's regeneration cycle was... too simple. Call me weird for thinking that, but [[spoiler: Clara begging the Time Lords to give him a new cycle and having it work seemed a bit too... easy. I was expecting a more complex method from Moffat.]] It's probably because that I wasn't the biggest fan of [[spoiler: Amy]] but her cameo right at the end did nothing for me other than remind me that she was his companion. Finally, the Doctor's regeneration happening in the blink of an eye felt a little off compared to the spectacular regenerations of the 8th, War, 9th and 10th Doctors. Some things worked in the episode, but it was far from perfect.
