Only watched once so far and with friends, so there was a lot of discussion going on at the time.
New titles; must listen to the music carefully, but did like the inclusion of the face and a better time tunnel.
Sherlock reference was fun, plus that was the Sherlock music.
So screamed when the ice Governess grabbed Clara.
Not sure why Clara was being given a key so early, but I do believe that this is the first time the Doctor has asked anyone to travel with him since Joan Redfern (Donna got herself on to the Tardis using a previous invite; Amy asked herself if she could come, as did Astrid; River doesn't really count with her timey-wimey ness.)
No one else has pointed out that the spiral staircase changes the way it twists half way up. It happens both times. Bad continuity BBC!!
Everyone in the room with me wanted Strax to be a companion (who is the friend who brought him back?)
I so wanted Clara to be Jenny (Doctor's Daughter), but now I'm wondering if she is something else entirely that has been split up, and facets spread through time. Thinking a bit like the Key to Time.
