So yeah, this final episode seems very familiar, since its essentially the 11th Doctors final episode too.
The doctor has to fight an endless war against cybermen with only a lone cyberman as his most loyal companion? Ok Bill is more than just a head like Handles was, but damn Moffat, you are the greenest writer on TV with all this recycling!
I really don't like that cybermen can fly, way too Iron man, but that's been there a while now, also a Moffatt invention I believe.
The Missy Master betray I saw coming a mile off, I guess that's why a multi Doctor story is more viable than a multi Master story, their instinct for betrayal and murder even extends to themselves.
I liked the saving of Bill, a good call back to the first episode of this season, and leaves the way open for her to come back, now that she is essentially a tardis herself.
Now I am going to need help on this one, but I could swear when the doctor buried his hands in the snow and stopped the regeneration, for a second I saw Matt Smith's face, anyone else?
That ending though, Dave Bradley FTW.
