In Dr. Who the directors do a very good job of the diversity of gender in the show, with the companion usual being a female. The only place we haven’t seem gender diversity is the the Dr. The Dr. is always male, but even though the Dr. has not been female, many major roles are played by females. I have also noticed that many topmost of the alien leaders are male as well. So, I think the BBC does a very good job of keeping the role of females in the show are quite equal.
