I liked it as a three parter. Good suspense. I like the Monks as monsters, and I like that they were left somewhat mysterious. I hope we'll see them in the future. I'm liking Nardole a lot. And even Bill was ok, particularly in this last episode.

One thing that is bugging me about this series is incidental music. There's too much of it. It's a feature of New Who in general, but it seems to me to be getting worse.
