In the 'Whoniverse', what is so special about Christmas?
There is just always a Christmas special, and it's the only new Doctor Who in between the exceedingly long breaks between seasons, which in my opinion is getting a bit ridiculous
The majority of the Doctor's companions have been from English speaking countries of Earth where Christmas is part of the culture. I think the Doctor likes the festival in the same way as some people like certain kinds of music.
What do you think?
