Ugh, clichétastic villain.

So that's the new opening sequence. Meh. Don't like how it sounds. Look is okay. I'm glad they didn't make the Doctor's face all in your face.

Dr. Doyle writes about an alien detective and her wife. I'm sort of amused, but also annoyed.

He never helps anymore, boohoo. There is no "anymore" with a time traveler! Is my grumpiness showing? I can't help it, I have no hope for this episode. The Christmas specials usually disappoint.

Why (and also how) is the TARDIS in the sky? What's with the ladder?

Ooooh, Annie from Life on Mars!

The Intelligence?! Ahahaha, I've just watched these Classic Who episodes! And the Intelligence's first story is called The Abominable Snowmen, hehe.
"Takes one to snow one", okay, I laughed.

And here we have the obligatory Doctor-companion kiss.

Meh, new TARDIS interior.
"It's smaller on the outside", ha!

Has anyone ever gotten the TARDIS key faster than Clara?

Well, this is gonna be interesting. Clara actually fell to death. Yo Doctor, you have a timemachine, why didn't you travel back in time to catch Clara?

What, Clara's death isn't solved in this episode? This is going to stay interesting, then.

At the graveyard we get references to the 2 previous Intelligence stories, hee.
Oh, I forgot that the Doctor never saw Oswin. Turns out Clara is Oswin, aha! But how? Is this our next story arc? Oh, hey, so there we are again at the grave of someone who fell to death. And who isn't actually dead. And we have yet to find out how that's possible.

Looks like the actual companion will be another version of Clara *sigh*. Because I liked this episode's version.

Well, this episode wasn't bad! Actually it's probably the second best.
