I’ve decided that there is really only one person to take over the Doctor Who role.
If for nothing else than to watch the heads of clueless fanboys explode in righteous indignation at the casting of an American actor, only to have their shame further deepened by learning that he’s really very, very British.
Also, I think Doctor Greg House with a time machine would be sweet. He’s already got a bunch of companions who respect him but rarely understand him. He has metric tons of gadgets at his disposal. And he has a total lack of respect for authority.
Someone get marketing on the phone, stat!
(And really, would my idea be any worse than this? I think not.)
