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.
Renita: Doctor Who 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 Magnificent Bastard to a Dalek pet just to sate the wrath of the Fan Dumb that objected to him ever overshadowing his creations despite being far more interesting than they are.
Loquacia: The realisation 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...
Gentlemens Dame 883: 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.
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 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 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 wan't so bothered by Ten saying goodbye as I was by the fact that his regeneration somehow flipped the Self-Destruct Mechanism 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.
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's true form is revealed to be a complete ripoff of Fat Bastard, to the point of even having a similar-sounding accent. It doesn't stop, either; the villain is an alien which absorbs other sapient entities. The protagonist's partially-absorbed love interest's face is sprouting out of its buttock. But by far, nothing tops the infamous line "We still have a bit of a love life." It's spoken by the protagonist—with regards to him and said love interest, who is now just a disembodied face protruding from a concrete tile. How nobody even considered that might be offensive, I will never know.
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 And I Must Scream 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 A Fate Worse Than Death so Rose can complain.
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 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.
Dark Hero 9: 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 The Bad Guy Wins 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.
Dynamite XI: 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 Bad Future and still managed to change it (at least twice, 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 Esoteric Happy Ending. Anyway, this episode certainly killed Season 7's good vibes.
Novus Wulf: To add my two cents to this, had they (Amy and Rory) died when they jumped off the building, I would have said they at least died with dignity. But NOPE! Instead we get a pointless sequence of Rory getting bumped off from behind and Amy kamikazing herself onto a Weeping Angel. Which was just plain stupid. Even Adric died with more dignity than this.ADRIC!
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 Mahattan looked at it in the entire time it was taking a stroll?
Tropers/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 episodes 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 Doctor Who 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, threw their hands up in the air and said "We don't give a damn!" Give me the charm (mediocre special effects, So Bad, It's Good acting) of the old series over this childish excuse of a Doctor Who episode any day.
Tropers/Dragonmouth: The big reveal of why Amy and Rory are getting a divorce. Amy says she left Rory because 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 inability to have children. She should have had an honest discussion about 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 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 Idiot Ball, 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 Excuse Plot 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*
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! 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, which featured Clara Oswin Oswald. So much for it being filler.
Telepresent: The episode wasn't filler, but the whole divorce business certainly was...
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.
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 John Hurt 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? 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 "Clara is destined to save The Doctor!" reveal. Or, to put it bluntly, they turned Clara into one big Mary Sue. 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 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 Purity Sue 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 "Dalek Oswin". At least she was more interesting and compelling of a character than little miss Mary Sue here.
Calamity2007: Also the reveal that the Toclafane are 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 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.
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 Canon Sue, being birthed fully formed with Time Lord intelligence and Action Girl 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 And the Adventure Continues.
Tyler FG: Now, I had high hopes for the Day of the Doctor, I really did, but the whole fact that 9's storyline, and some aspects of the 1st and 4th seasons, and The End of Time are rendered moot due to the fact that 10, 11, and the War Doctor all decide to bring Gallifrey back and undo the entire Time War. Ok, never mind that the Doctor did it to stop the Time Lords from becoming as bad as the Daleks, (This is even stated in the Night of the Doctor minisode!) or that he was coming to terms with what he had done, and how he had basically killed his own people by force. No, fuck that! Let's just destroy nearly all continuity we had built this entire arc up to so we can bring Gallifrey back! I can only hope that Russell T. Davies is just as pissed as anybody else would be by this piss poor excuse of a "anniversary special". (Which I use very loosely, since only Tom Baker, which was a great cameo, and David Tennant come back. And no, showing stock footage, and random props do not count as an "anniversary special".)
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 that 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, none of the established rules ever came back after that episode. I was even pissed at the Ninth Doctor calling Rose a stupid ape for saving her father from the accident, even though she did it because she wanted to get to know her father. Seriously, I nearly lost my sympathy for the Ninth Doctor when he regenerated!
