Well, since I said much the same about the Freema/Martha eps of both DW and Turchwad last year I can't criticise. And I am hoping that "the Doctors'[1] daughter" makes a reappearance (she is srsly kewt, and having her regenerate at the end of the episode was apparently Moffat's idea so he presumably Has Plans).

[1] Yes, the plural possessive is correct. She was not only "the Doctor's daughter" in the episode, but the actress is the Real Life daughter of the fifth Doctor.
