Yeah, The Girl in The Fireplace reference, as well as the reference to how the Doctor has seen his face before (as in Fires of Pompeii), were both great! And the last scene between the droid and the Doctor was fantastic, very dramatic, and the mystery of whether or not the Doctor pushed him out (I think he did).
Yes, I watched the premiere and I thought it was fantastic! Matt Smith is my favorite Doctor (by a small margin), and I was a little worried about Capaldi, but I thought he did great! The episode itself was pretty standard, but still quite good, and right on track with the great new Doctor introduction episodes. What did you think?
