I'm not insulted. He just took the established fact that there were Doctors before Hartnell and ran with it.
It was an established fact that there weren’t. (Impossible astronaut, day of the the Doctor, and… the Matt Smith finale whose name temporarily eludes me depend on it to a great extent, and every multi-doctor story does.)
And the insult wasn’t necessarily to the audience… just to rather a lot of talented people that had come before.
It was executed in a way that made ‘dumbledore was gay’ seem like MCU levels of planning and foreshadowing.
(Don’t worry! Look! See! The doctor has always been inclusive, we just didn’t know that before he was some brain addled old white man, he was so many various girls and ethnicities. Non speaking of course, because have to keep the budget down on the token — I mean representative roles.)
And what is really annoying, is that Chef!Doctor (I really liked that series. I still think of the salmon tracking gag to this day.) is really good, better than Jodie in terms of costume, character, the lot. (I’m not commenting on acting, because you can only work with what you’re given.) I mean I may not like Kung-fu doctor stuff, but Pertwee happened yonks ago.
But there are ways of doing that which could have been interesting, and built something, without tearing stuff down. Being in a parallel universe has been tinkered with in who before, on and off screen, and that would have been better. We could in that way have even kept the development of missy.
Instead we have… this.
