I stopped watching after the first episode of the lady Doctor. Now I don’t think I will resume.
What endeared many viewers to the Doctors was their occasionally being silly clowns. Especially Matt Smith, in his interactions with River Song.
With the female Doctor, writers could no longer have the Doctor be comic relief, or less than “perfect in every way”.
With a gay black doc, it will be similar.
I stopped watching when Capaldi’s doctor had the mouthy gay golliwog as a companion.
