I watched the episode yesterday and I have to say I liked it. The whole "metaphorical Santa is actually your subconscious but actually not because he's real" thing was a little bit odd, but Nick Frost was a great Santa and overall the episode was a good one. I'm glad that Clara is staying for a while more, I never liked the way they parted in the ending of season 8 because it seemed like a bit of a forced exit. Also, as soon as she got attacked by the dream-insect-thing (can't remember the name for the life of me) I called that she was gonna end up killing herself so she could live with Danny so I'm glad that they anticipated that guess and made sure it didn't happen.
