Matt Smith.
Yes, he’s young. The youngest-ever at 26, in fact.
Yes, he’s got an “emo-ver” haircut… and, if that’s the costume (unknown at this point), it’s all a bit “Twilight.”
HOWEVER —
Since seeing my first pictures of other Doctors after watching Tom Baker for years, I’ve always been skeptical of a new Doctor’s “doctorishness” — and they’ve *always* won me over, usually in the first few minutes of their performance. I have no reason to believe that the same thing won’t occur with Eleven.
Plus — Steven Moffat is writing him. That’s all I need to know.
