Details: Aired on the BBC in 2017. About an hour long. This is the Christmas special.
And so we’ve arrived at Peter Capaldi’s last episode as the Doctor. This final episode is our opportunity to take one final look at Capaldi’s portrayal of the Doctor. It is also Capaldi’s opportunity to say his goodbye and leave his final thesis on who his Doctor was meant to be. While there were some episodes in Capaldi’s tenure that I did not enjoy, there were some that I did enjoy immensely. Twice Upon a Time was a surprisingly emotional goodbye to a Doctor who was not as good as his predecessor (in my opinion), but left a meaningful and distinct mark all the same. It is also a goodbye to the Moffat era of Doctor Who.
