The episode was... fine? I am a big fan of Doctor's second episodes. Even when they aren't great, I have a real soft spot for them. The End of the World, The Beast Below and Into the Dalek are some of my personal favorites. This wasn't up there, though I did like it enough I guess.
The show feels low energy now. What feels weird to me is that it is like Jodie is trying to give the show energy, but the rest of the show, including the writing, isn't keeping up. Even Jodie seems to be trying 11's childlike wonderment, but in a very oddly low ebb world. It's like it is trying to be slow and deliberate, but without much actually to it. Over nearly 2 hours, I can't say much has happened. I am hoping Chibnall isn't writing every episode this season.
So is next week's episode about Rosa Parks? If so, they best tread carefully.
