My review of last week's episode: World Enough and Time.
(This is a long review. You have been warned.)
Well, here we are. And I'm conflicted. On the one hand, The Doctor Falls is perhaps the clearest, most concise Steven Moffat finale that we've seen. But on the other, it's deeply unsatisfying.
Mostly because of Bill. Moffat wrote Bill Potts into a corner so dark that he couldn't break her out of it without a Deus ex machina, and that's a problem.
