Maybe because of “The Hitchhiker’s Guide to the Galaxy”, “The Hobbit”, and “Sherlock”, I can’t see him in this role. He does well as the character that is always a bit befuddled. But if he got the role, I would watch.
Dr Who has long been played as slightly befuddled, as a result of a jumbled timeline and multiple regenerations. The past few doctors have forgotten that, but it’s essential to his character.
