Best Smith episode yet. I thought this one had a real 'old Who' feel, with some nice nods and references to the Doctor's past, and some great character moments from the doctor and Idris.
So we finally know the Doctor could regenerate as a woman.
Great to see what a real writer can do without lots of bangs, flashes, and 'look at how cool this is' grandstanding.
Gaiman was geat on Confidential, he seems to have a real understanding of what makes the show tick, and was actually interested in telling a story. I wonder why Moffat looked so subdued in his 'blink and you'll miss him' spot :angel
