I should start this review by providing a little bit of context: As a generality, I don’t like the Christmas episodes. Most of them are schmaltzy and overly trite. I don’t even like the idea of Doctor Who doing Christmas episodes. So it is with that bit of information fully divulged that I declare openly how much I loved this episode. It’s not only the strongest and most enjoyable Christmas episode we’ve had, it caps off the strongest season of modern era.
