Jody Whittaker's stories were too preachy and clunkily inclusive: not only the first female Doctor, but also an Asian female companion, a black male companion who was, though not obviously, disabled, and an older, white working-class companion, whose late wife was black. One or two of those elements would be ok, but all of them at the same time was over-egging the inclusive pudding a bit.
Richard Ayoade for the next Doctor? He's been suggested, along with a black female actor whose name I can't remember, and a couple of others. RA would be excellent.
