Agreed, Jimmy. Catherine Tate is a perfect example of casting someone who may not be "pretty" in a young-skinny-sexy way but who was fantastic in her role. Fuck, Baker wasn't pretty. He's an ugly bastard, yet he's so many people's favorite Doctor.
Agreed. I think Capaldi is a great choice, for many reasons, but he reminds me so much of earlier Doctor actors and it might be a return to that style of storytelling.
Also, I think we might see a return of the Doctor's intolerance of human stupidity, much like Gandalf and his dealings with Pippin in LOTR.
