Lest we forget how many people world-wide instantly adored Tenn*nt, or Sm*th, or even B*ker, or D*vison before they’d even seen ONE SINGLE IOTA OF SCREEN TIME. I think the only complaint people had about Capaldi was his age, and that was mainly just those who weren’t exposed to the Classic series. There is absolutely no way to pretend it has nothing to do with the incorrect perceived notion of the Doctor’s ‘gender’ like that’s a thing.
