The best Doctor Who special, Christmas or otherwise. A lot of backstory in the Amy and Rorie scenes technically, but doesn't feel like you actually need to know the show to like this.
I've watched this at least once a December since it came out, but since I'm sick this year and not drinking: why are there no fish biting when he says they are? Did they leave out an effect? How do you miss that?
