I LOVED Capaldi. He did so good. Aside from a few things, so happy to have an older doctor be present again. No more 2000-yr-old dating a 20 year old. It's a miracle!
To me , the episode was ****. The opening half an hour was just family-style comedy which doctor who was never designed to be. Witty jokes are fine , but the just stupid family-dinner kind of jokes... nah.
