A Christmas Invasion Night Thread (12/16)

It’s December so I’m doing some Open Threads on Doctor Who Christmas specials. (this is the last one!)

This time it’s A Christmas Invasion.

It was the show’s first Christmas special since its revival and the first Christmas special starring Tennant as the Doctor.

Basic synopsis: On Christmas Eve high above London, the alien Sycorax are holding the Earth for ransom. The Doctor must recover from his regeneration in time to save the human race.
