1. How did Missy/Master get control of the Cybermen?
2. If people are cremated, then how are they turned into Cybermen. There isn't a corpse to be upgraded?
3. How did the Missy/Master survive the end of time?
4. Why lie to the Doctor about the location of Galifrey? It makes no sense just to fuck with him like that.
5. How does UNIT always know who is the Doctor? I personally think it takes some fun out of it.
6. Did they just rehash the Sontaran invade earth storyline and how to stop them? "We're turning Earth into a breeding ground via something in the air and then is stopped by someone expoding and sacing themselves to make the sky clear again"
7. Now, this is probably going to make me sound horribly racist but fuck it. Why did Pink work so hard to bring that kid back? He died in a warzone. It wasn't some accidental death in a no combat zone. All Flash backs we saw of him in battle were of shit getting serious. Not saying the kid was attacking them or something but it's a question.
8. Why did the Cybermen sound so shitty this time? I used to love their voice but this time it was just shit.
9. I can understand why the Doctor lied to Clara but why did she lie to him? She could have had the Doctor even return the kid to his proper time a few minutes after his death. Pink even said the kid has been dead for sometime. So, sure, he did the kid a solid by bringing him back, but, back to what? A family that would probably never accept him again because not every person knows of the Doctor and his time travel shit. Also, let's not forget that again, the kids been dead for some time. No way in hell that kid is stable enough to live a full life after dying from what looked like a Grenade in the flash back, living in what he thought was the afterlife, then being turned into a Cyberman, only to explode to stop the invasion, then be brought back to life some years after his death in a different part of the world. If he wasn't fucked up before his death, he sure as shit will be now.
I'm sure I have more questions but it's been like 12 hours since I watched it so I've forgotten most of the episode. but ya. Decent finale but just left way too much open in my opinion.
And again, they made it so the Master is pushing a Companion into the Doctors Arms. We already had this storyline in Season 3
Oh and I really help the Christmas special and the next season have much better writing or Doctor Who will have to take a 10 year break again.
