It's been a year since the last episode of Doctor Who and I'd more or less forgotten that I did quick reviews of them on this blog (TBH I'd also more or less forgotten about this blog but there we are.) Anyway this year's Christmas Special was fun enough that it was worth blowing the dust off.
"The Return of Doctor Mysterio" by Steven Moffat, directed by Ed Bazalgette. Spoilers after the cut.
