Doctor, Doctor
That's probably my favorite of all of the pictures they've released. He seems to have both a good and a bad side in photographs- he looks sort of weird in some, and good in others.
I haven't seen anything he's been in, though it's nice that he's already been in some things with Billie, because then you can get screencaps and such with them in the same shot. *shrugs* It's the little casting coincidences that make me happy, really.
I will miss Ten like anything, but I'll hold out final and less superficial judgment until we actually see him on screen. (But really, anything is going to be less painful than watching the current season of Smallville, amiright?
