I like this one, but you're right to think it's long. It's only *just* under an hour. It's Christmas special length, and longer than some of them (The Christmas Invasion, Widow/Wardrobe, Husbands). Even amongst the longer regular episodes of the CC era, it's an outlier. Every episode of Doctor Who longer than it is a Special, a Premiere, a finale or Spyfall Part Two.
