Agreed, also i don't think a female doctor would work, it breaks tradition and i never knew regeneration can change sex types, i just thought it was a survival mechanism.
I wouldn't want a female Doctor, I'd like to see it carry on as a male lead, as it always has been. Unless I missed something with a female turn...
If he changed, does that mean he would be interested in males or females? Since he can remember everything yes? so he would now be a she with feelings still for Rose...?
I don't know the rules of regeneration.
