I wasn't a big fan of Peter Capaldi's Doctor, until this season. I don't know if it was the writing, or the companions, but I so loved Nardol and Bill, they made this season, in my opinion. Well and Missy/Master was terrific. I have always had a love/hate thing for John Simms Master, and he did not disappoint. This was by far the best episode of the entire 12th doctor reign, although we sadly lost everyone at the end.
