Bill Potts felt, from start to finish, like an afterthought. Like she was just there because "the Doctor has to have a young female Companion" and for no other purpose. At least this wasn't one of the ones where she was Important Because Really, Everybody, We'll Contrive A Reason For Her To Be Important.
Sad, boring echo of Martha Jones, is all Bill Potts was.
The First Doctor being innately sexist likewise felt completely contrived. He was never like that until this debacle, where they made him that way, uncharacteristically, in a pitiful attempt at "Haw haw, he's antiquated and un-enlightened! Hawr!" Please. And come on, the WW1 soldier was a Lethbridge-Stuart? For fuck's sake, really?!
It was good to (sorta) see Nardole again, though. Stupid little bald fucker. He was one of the few tolerable things about Series 10.
It is interesting that the very first thing that happens to the 13th is she falls out of the damn TARDIS. Especially since the doors open inward, not outward. But whatever, now she can miraculously... fucked if I know, land on her tampon, or some shit, I guess.
As for the first episode of Series 11, I'll watch until the SJW-ness pisses me off, then I guess I'm done with Doctor Who other than from 1963-2016.
