@ Matthew Allen:
Yes, he is a bit creepy-looking, but as a friend of mine pointed out, it's Moffat who's in charge of the show now so creepy is to be expected...
In any case, I say give the guy a chance. The producers could have probably had their pick of any actor (or actress, but even as a girl, I don't think a female doctor would ever have been right) in all of Britain, and it's not like they had any need to expand the fan base by getting someone younger seeing how DT was 37 (to be honest, he doesn't look that much older than this new guy to me) and the show got spectacular ratings, so I don't think that they'd have picked an actor who'd be a poor fit for the part for any superficial reason like that. As far as the 'emo' goes, it's all in the hair, and that's probably the easiest thing to fix...
A smiley face, cause I'm kinda optimistic about this one.
