If it ain't broke, don't fix it...as the saying goes. Doctor Who is a successful show, and it would be foolish of the creators to cast a female, or a black person, in the main role just to appease liberals. Liberals want to ruin everything.
If you want to empower blacks or women, than start a new show featuring a black person or a woman as the hero character...and LEAVE DOCTOR WHO ALONE!
I think the Dr., just like James Bond needs to be moved into the past(get a DVD box if you're a fan, nostalgia shouldn't be remade over, and over), maybe TV, and Movie-studios need to come up with a new idea.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
