My view is that the British viewing public is fundamentally racist. I wonder therefore if the viewing figures will suffer from having a black Dr Who
So do I but I fear it might be!
Personally, I my main objection to recent episodes has been the extremely poor script writing. In my view there is way too much often very poorly recorded dialogue. It's supposed to be a kid-oriented programme and kids are not known for their tolerance of people rabbiting!
The same thing exactly happened to 'Killing Eve'. The first two or three series were addictive watching then they changed script writers and I watched one episode of the new series and I have never watched an episode since. Suddenly, it was all rabbit and no action!
@Paulos_the_fog I'm not as down on the Chibnall era as some but I do think that too many episodes contained long exposition dumps that are not dramatically interesting.
