Spoilers for future developments in Doctor Who I didn't want to know about and why under cut. Contains spoilers most of the world already knows.
Okay. I had been in moderately successful denial that Tennant is leaving after his contract's up. Today they picked someone new to play the Doctor. I don't want to know who. Really, I don't much care, as long as it's not Russell Brand.
I have been trying to push the casting news for the show out of my head because knowing that Tennant is leaving removes all the suspense from any peril the Doctor's going to be in for the last few outings. I know he's going to regenerate, in the last one, probably near the end. I know it's coming. Suspense and tension goes poof.
Now for the other reason Tennant leaving is distressing me.
I love David Tennant's Doctor. I have been watching Doctor Who for nearly twenty years (in repeats) and had always considered Tom Baker to be "my Doctor". Then briefly Paul McGann because that cracky little outing was the first new Doctor Who in years, but I slid back to TomDoc. Then along came the new series. I liked Nine, but not enough to swap allegiances.
Then along came Tennant.
David Tennant's take on the Doctor has been... I don't know if I can explain this. His Doctor has been the Doctor I've known in my head since I started getting into the show. I know opinions vary on his portrayal but this is my head and my opinion. Tom Baker and all the rest did wonderful jobs, but somewhere around the start of series 3 I realized that, for me, Tennant had replaced all of them. Like the rest were just placeholders until the real Doctor came along.
Ten is my Doctor. And knowing Tennant's leaving the series feels like my Doctor's come down with a fatal, incurable disease.
I know it's absolutely ludicrous for this to be depressing the hell out of me but it is.
That said, I haven't seen the 2008 Christmas special yet, and I don't want to know anything about anything related to Doctor Who occurring or influencing any episodes or specials past 4X13. I wish I didn't know what I do know. :-P
