An attempt to be relevant
Nearly all the Doctors have been played by fine actors, each brining something to the role. Well, perhaps Silvester McCoy really was out of his depth or maybe it was having to work with Bonnie Langford? The problems have always been related to poor writing.
Jodie Whittaker is a fine actress and, unlike say James Bond, there's not a long particularly masculine in the role, so there shouldn't really be any problems. Still, it's going to take some excellent writing and production to overcome any prejudices or suspicion of tokenism that the decision was taken for PR as much as anything else.
