A tense and at times terrifying episode shot through with an undeniable sense of dread. Dread because we know some of these characters are doomed. Dread because we know we will not be allowed to understand the Midnight creature.

I appreciated the brief but necessary levity on the TARDIS and into the mission. Because the rest was heavy. Belinda has seen the death that follows the Doctor. Now she has seen the cosmic horror he meets with joy. “You’re dangerous,” she said in The Robot Revolution. What could she be thinking now?

I’m sure I’ll have more thoughts once I’ve sat with the episode
