For me: bland writing, uninteresting villains (or at least, the ones that could be brought back weren’t interesting enough or weren’t actually villains), and too many companions taking focus and development away from the Doctor, leaving her to feel rather bland and one-note despite Jodie’s excellent performance. (Please get rid of Ryan…)

They should keep up with the historicals, though. Witchfinders, Demons of the Punjab, and Rosa were all the standout episodes this season. But they should probably drop the shoehorned sci-fi elements in those stories and go back to pure historicals if they’re gonna keep doing them - Witchfinders is the only one where that really worked for me (it was particularly bad in Rosa).

The only non-historicals I really liked this season were It Takes You Away and, to a much lesser extent, The Tsuranga Conundrum.

But the biggest criticism I have is, as I said, the one-note writing for the Doctor. She has the boundless enthusiasm, wide-eyed wonder, and deep empathy, and…that’s it. Where’s the ancient alien who carries the guilt of all the terrible things she’s done? Where’s the Oncoming Storm bubbling beneath the surface? The clever manipulator?

It seems like they were so afraid of people criticizing the first female Doctor that they stripped the character of any of her shades of gray, leaving behind a lot of nuance and complexity that nearly every Doctor has had before her, and giving her essentially no arc whatsoever throughout the season.

Hopefully now that the companions have been established and will all be returning, they’ll spend more time developing the Thirteenth Doctor (and I guess Ryan too if he has to come back).
