Leave it to Doctor Who head writer/showrunner Steven Moffat to pull out a surprise from his bag of tricks, as a previous incarnation of the Doctor makes a sudden re-appearance in this "mini-episode" titled "Night of the Doctor".
So much talk has been made of how the 50th anniversary special would be a celebration of Doctor Who's history, but that it would also move it into the future and a new era. From the looks of this prequel, it does appear that the Time War storyline - something that has been lurking in the background since the show returned with Chris Eccelston and Russell T. Davies - is finally going to be addressed.
And then it's onward!
Were you as happy to see the return of this version of the Doctor as I was?
