Dang it, Moffatt.
The 50th anniversary special managed to be both lighter and darker than the average Who episode. The incredible bouncing Fez, an appearance by Tom Baker's scarf...
High notes were the beautiful chemistry between David Tennant and Matt Smith. Not only did they utterly convince the audience of being the same person, to the point where on occasion I almost lost track of which was which (especially given their similar build). Billie Piper's performance was incredible - and no, she wasn't playing Rose Tyler. Oh, and you won't believe Who shows up at the end. Maybe.
On the dark side, the story addresses the Time War, the Doctor's crimes and, shall we say, the fluid nature of time. The book the Doctor is reading at the start is a perfect Chekhov's gun.
On the vague off chance there was somebody under a rock all weekend who still has it sitting on their DVR unwatched, I'm not going to say any more. I will mention that it will be going into the Guinness Book of Records - as the non-sporting television event shown simultaneously in the most countries. 94.
94. We may get fifty more years of this show. I certainly hope so.
