I think that “The Eaters of Light” is often overlooked, but I really enjoy it. It’s an episode that has so much room to breathe that the guest characters get more definition, and the leads have time to talk. And there is music and ghosts and ghost music.
It was written by Rona Munro, who had previously contributed “Survival” a ridiculously long twenty-eight years previously, and is one of many, many stories that so many people have written to solve the mystery of what happened to Rome’s Ninth Legion. Well, you and I know that they ran into a wall of extremely pissed off Picts, but it’s more fun to lose them in time or space or have a space monster eat them. It’s really nice that the Doctor and Nardole get more screen time together than they had up to now in this one, and Bill gets to show off some of the lessons she’s learned in getting people to work as a team. It’s a very, very good episode.
