I'm all for giving the guy a chance but I'm a little trepidatious about having a 26 year old as the Doctor. I could deal with a mid to late thirties Doctor but any younger than that just seems at odds with the resposability and experience that goes with being over 900 years old.
Still, I'll just have to wait and see how it plays out. Hoping for the best.
I know that a lot of people were very cautious when Peter Davison took on the role because he looked so young compared to a lot of his predecessors. (And coming after such an iconic Doctor what was portrayed by Tom Baker - hmm does all this sound familiar?)
But I think he pulled it off, there is something about a young person playing an old personality that if Matt can do this will come across really well, imo.
