I really enjoyed it. David Warren has become one of my favorite people to pop up in things, because he always brings his A game. The Hungry as a Wolf thing was hysterical. I loved how the ship bowed to the Doctor at the end. So far, this is season is doing a nice job of making sure the next episode is better than the last one. I loved Clara wearing the headphones, it was god damn adorable.
