When this season’s available as a binge watch you’ll forget this gap ever even happened. We’re here to discuss the first half of the “Doctor Who” season finale, which is a little like reviewing the first half of a book or movie. What will happen next week? We have endless theories and no hard evidence! Are these red herrings we see before us? Why is the Lone Cyberman so effective as a villain? Ko Sharmus isn’t a planet, he’s a person! Bring on Barack Stemis. Host Jason Snell with James Thomson.
