Exactly! He’s going to be the eleventh Doctor Who!
They went the route of casting a relative unknown, which is not unusual. Nevertheless, fans being fans, the announcement had barely been made before people were bitching about what a bad choice it is and how wrong he is for the part. Ah, geeks!
I’m almost certain that, should one care to dig, you’d find the exact same things being said about David Tennant in 2005. Griping about the new Doctor is part of the process, I suppose.
For me, I’ll reserve judgment until I, like, see the guy in the role. I wish him the best of luck!
(Incidentally, Twitter was all a-twitter with the announcement: http://search.twitter.com/search?q=brave+choice.)
