The Return of Doctor Mysterio (S09E14)

Some sagas can't deliver the development of a superhero even in a trilogy as convincingly as Steven Moffat manages in just an hour. With the Doctor's one-year absence combined with perfectly cast Justin Chatwin, Peter Capaldi's sorrowful gaze, and his usual playfulness, even though it is definitely the weakest special in competition with the last few years, it reliably spread an optimistic and comic mood in our home.

I don't know what's sadder: the fact that this is the weakest (but not weak) Christmas special in many years, or the fact that it's still almost enough to be the comic-book film of the year. By far the best part is the prologue, it's the pure essence of the Doctor. (12/26/2016)
