Working Titles

  • [no known working titles]


There’s nothing Christmassy about this one and everything is rushed beyond belief it is hard to remember what just happen in the previous scene. The plot jumps around as if it doesn’t know what the main focus should be, and nothing is tied together nicely. The episode is not really that funny or fun and some moments are surprisingly dark, even for the show’s standards. The whole Doctor-River Song relationship finally finishes but can be confusing if one were to begin watching the show after Silence in the Library and Forest of the Dead and for those who have not seen it. There is some nice design and heartfelt moments, but it does not live up to previous Christmas episodes. **​
