“Everyone gets stuck somewhere eventually, Clara. And everything ends.”
And so, Christmas Day 2013 saw the final end for Doctor number Eleven – or is it Twelve, or even Thirteen? That was one of the major questions Steven Moffat’s typically labyrinthine but mostly satisfying story had to address; along with the various unresolved plot threads that seemed to have been left hanging since he began his tenure as showrunner. He also had to retire the now-beloved Eleventh Doctor and introduce a new star .And on top of all that, he had to make it a Christmas episode, traditionally lighter and frothier than most.
