It's stylish enough, and even a little substantive for the standards of Chibnall. In spite of others liking it I don't really get much out of this episode. It's fine. Unusually coherent for a 13th Doctor episode, but still kind of pointless. Ashad has some of the biggest build-up of any Doctor Who villain ever and it really feels like it doesn't amount to anything. He's just going to get tossed away in a couple of episodes. Who cares?

It reminds me a lot of some of the stuff we've heard about what production was like during this era. Rushed, to the point that scripts were delaying filming - and the writing shows for it in stuff like this. I bet people could watch this and be disengaged enough and unable to follow things to the extent they would have no idea Frankenstein's writer was involved in the story at all!
