History YMMV / DoctorWhoS34E12DeathInHeaven

** Fans were also adamant that Missy killed a [[Recap/DoctorWho50thASTheDayOfTheDoctor Zygon]] and not the real Osgood. The Zygon [[Recap/DoctorWhoS35E7TheZygonInvasion two]]-[[Recap/DoctorWhoS35E8TheZygonInversion parter]] from series 9 would eventually confirm that there were two Osgoods, but doesn't answer whether Missy killed the human or the Zygon.

** Fans are also adamant that Missy killed a [[Recap/DoctorWho50thASTheDayOfTheDoctor Zygon]] and not the real Osgood. Which was later confirmed in 2020.

** The morality of all things Clara.

* BrokenBase: As is customary for nearly every ''Series/DoctorWho'' episode. In this case, the break is between those fans who thought the Brigadier's return as a Cyberman was a touching tribute, and those who thought it was in the worst possible taste. [[ArsonMurderAndJaywalking Or for some people, the concern was he lacked a moustache and a UNIT uniform to signify that this really was the Brig.]] Others loved the fact that not only was the Brig back, but he could now fly and had laser beams.
* HarsherInHindsight: Missy's quote on killing some Belgians because they're not French is now hard to take humorously, because two years later, there came the Brussels bombings courtesy of the Islamic State.

** Fans are also adamant that Missy killed a [[Recap/DoctorWho50thASTheDayOfTheDoctor Zygon]] and not the real Osgood.
*** Creator/IngridOliver, Osgood's actress, [[http://www.bbc.co.uk/programmes/p02b9fpy would certainly like to think]] her character's just hiding. (It was later confirmed that Osgood would return in Series 9.
** Missy had been using her disintegrator device to blast people into a fine red dust left and right. It seems kind of odd that the same device disintegrates her into a fine blue dust instead, not unlike her teleportation earlier. To this, many point out that the reasoning is because the device itself wasn't used to disintegrate her, with it instead being the Brigadier's Cybermen artillery that did the job. That said, Moffat himself enforced this trope with his comments immediately after the episode aired, noting that he hoped Missy would emulate Creator/AnthonyAinley's Master in reappearing without a scratch after getting involved in DeaderThanDead situations. Wouldn't you know it, she turns up fine in the next season premiere.
** Since Seb isn't actually alive, but an A.I. interface, it's unlikely he would have been "killed" when Missy used her disintegrator on him in the Nethersphere. This, in turn, provides a small HopeSpot regarding Osgood's survival.
* MoralEventHorizon: Invoked by [[http://www.denofgeek.com/tv/doctor-who/32928/doctor-who-steven-moffat-on-series-8-missy-lies-and-leaks Moffat in an interview]], who is well aware of Missy's DracoInLeatherPants tendencies. He had her kill off fan-favorite Osgood to remind us that just because she's a woman now the Master isn't any less of a psycho than she's always been.

* UnexpectedCharacter:
** Seriously, who thought for one minute that ''Santa Claus'' would show up, especially in an episode like this?
** While many fans correctly guessed major elements of this episode, no one saw the Cyber-Brigadier coming.

* TheyWastedAPerfectlyGoodPlot: After spending the last two seasons playing out in the background, the fact Missy orchestrated the Doctor and Clara getting together is still, ultimately, pushed into the background by the whole "make every dead person on earth a Cyberman" thing. Also, considering their deaths were the emotional centre of Series 7, the fact neither Clara's mother, nor Amy and Rory, are even mentioned feels like an omission given that the fact the Brigadier is revived implies that they might now be Cybermen, too.

* SeriesResemblance: Almost certainly unintentional, but you really can't deny that this episode centers on [[Franchise/MassEffect an aeons long conspiracy spanning the course of civilization to use ancient alien technology far beyond human understanding in order to convert humans and other sentient beings across the universe into techno-organic zombies.]]

*** It's been confirmed that Ingrid Oliver will return as Osgood in Series 9. That's all that's been confirmed for now...

** Any shot of the Cybermen taking off into the sky looks extremely fake. They also looked like a bunch of Iron Man suits taking off.

** It's more clear than ever that the Cybermen's suits are made out of rubber. Especially in the beginning when people are touching and hugging them.

*** Darn it, I do now. [[CantUnhearIt Can't unsee it]].

** Danny's final ReasonYouSuckSpeech - Correct, deserved, understandable bitterness in the face of death and betrayal, the former but [[MurderTheHypotenuse directed at the wrong person]] (in the sense that he should be upset at ''Clara'' for lying and not putting him first), or [[SoreLoser unnecessarily petty]]? Or intentionally being too harsh in an attempt to make the Doctor dial it back, for Clara's safety?
