The 2017 Christmas Special gives you three Doctors for the price of one disc.
It’s the departure story for Peter Capaldi, who’s facing a regeneration crisis together with his very first incarnation (brilliantly played by David Bradley, channelling William Hartnell). Then of course there’s the introduction of Jodie Whittaker’s 13th Doctor. But before we get to that historic gender switch, there’s the matter of a disrupted timeline that has displaced a World War I soldier (Mark Gatiss), the appearance of a soul-harvesting spaceship called Testimony, and the seemingly impossible return of Bill Potts (Pearl Mackie).
Twice Upon a Time is a cracking regeneration episode, with the Christmas theme dialled down (thank goodness) but nicely integrated, and a poignant farewell speech from Capaldi. Now it’s not a case of who’s next, but what.
