There's no question in my mind that it'll still be Doctor Who, but an audience whose understanding of the show begins with "Rose" and has experienced the show's openness to change only gradually? I think they might well be thrown off their stride by the new team changing everything at once. The only comparable example in the classic series is the Troughton-to-Pertwee transition, and at that time Doctor Who was a low-rated show under threat of cancellation, so there was reason to believe the audience wanted all change.I'm surprised there's even a question in people's minds that it'll still be Doctor Who.
We've had new Doctors before, and it's not like the new producer isn't familiar with the show...![]()
If the new team wants to make these changes, it will, and good on them, but I doubt series five will be the time it all happens.
