She wasn't really the main problem. I was down for a female Doctor, just like I was down for a female Jedi lead in the Disney SW trilogy. Like that abomination, it was the awful writing and agenda-driven showrunner Chris Chibnell that ruined Doctor Who. I just watched her in a BBC detective show called Broadchurch. She's excellent in it, amazing series, and I believe Chibnell was the showrunner there.
In fact, the best Doctor is in Broadchurch with her, along with many other DW actors.
It's crazy how great that was and how terrible her run as the Doc was.
She did herself and the series little service by shitting on the fans when the ratings started tanking. It didn't help either that she did little to no research on the series, or the previous Doctor's. She and Chibnell weren't fans of the show, but like Nick Meyer proved (director of Star Trek 2 Wrath of Khan) you don't have to be a fan of what you're making, so long as you put in the love, care, and time to understand it.
Her and Chibnell's run with Doctor Who was 90% beyond far left politics. I know I've taken some pot shots at your politics, but believe me man, from the writing room, to casting, this was agenda over anything. They butchered the lore so badly, I don't think it can be salvaged. It needs a long pause at the very least.
This is the epitome of get woke go broke.
