Not being able to sleep at 5am this morning, I decided to check out the Dr. Who Christmas Special. Overall I give it a thumbs up. The story felt like a kind of typical regeneration story, with David Tennant making his first real appearance as the Doctor. I think he's going to make a pretty good Doctor overall. I won't discuss any of the content so as not to spoiler people, but I do recommend downloading it if you can (along with the children in need special, which you should watch first if you could).
