Well Now you have to Catch up. They just announced the new Doctor today.
I find this humorous as a years ago There was a Dr. Who Parody called The Curse of Fatal Death where the Doctor is forced to Regenerate 4 times due to a running gag. Starting with Rowan Atkinson as a a 9th Doctor. and Landing on a 13th who bares a resemblance in Hair, eye and physical description although a bit more mature.
I've been watching Doctor Who since 1973, when Jon Pertwee (who during WW2 was in the RN and had been a member of the ship's company of HMS Hood until a month before she was sunk) was the third Doctor. My earliest memories of the show involve the Giant Maggots from 'The Green Death' and a year later I became truly Arachnophobic after watching 'Planet of the Spiders'. I was four at the time. I'm cured now. Long story. Nevermind, moving on...
I haven't missed an episode in all that time, and have managed to see most of those from the sixties too. My point being I have perspective on the show. A lot of the disquiet about the new Doctor is coming from those who only jumped on the bandwagon in recent years. They have their favourite Doctor, and seem to think that means they have to disparage all the others in order to appear cool and knowledgeable. It actually displays their own insecurity as I see it. The Doctor is not any single one of those personas, The Doctor is ALL of them, they are all aspects of the same person. We all have many sides to who we are, show many faces to the world at different times, perhaps not to the same extremity, but then who among us has reached the age of 2000 years old?
So many on the net seem concerned about what is between the Doctor's legs now when the character has never been much bothered about those parts himself. He's not Human after all, and finds our petty obsession with gender and sexuality very primitive. He likes us anyway. Must do, keeps hanging out with Humans.
For 'fans' who absolutely need the Doctor to be played by a white male, well you only have 36 seasons of the show to watch again. I'm excited about the future, I like strong female characters, all the way back to Ellen Ripley and beyond.
The Doctor can be anyone, but whoever they are, they are still 'The Doctor', never cruel or cowardly, always kind, always merciful, and never one to surrender. This is the 21st century. Shouldn't that be a good example for girls as well as boys?
