Well, I just got done watching the this year's Christmas Special, The Next Doctor.
I found it very enjoyable, not the best special, but very solid. I liked the focus more on Morrisey's character than the Cybermen, and I'm glad it appears he won't be taking over in the future as the Doctor. I was a bit skeptical of another Cybermen story, but it was handled very well. The nod to the past Doctors was pretty awesome, but the best moment had to come at the end when the Doctor finally admits that his heart keeps getting broken by people leaving him. The only negative was there was no preview of any of the special coming out in 2009; I can only assume it's due to a lack of any filming.
"I assure you, whatever the others promise to do, when it comes to the showdown, they won't be there."
