Tennant was a fantastic Doctor and it would have been great to have him play the role for a couple more years. Smith will have a hard time following in his footsteps. But a lot of people were skeptical of Tennant when he was announced as Eccleston's successor and look how that turned out: Tennant is now considered one of the best Doctors of all time. So let's just wait till Christmas when we see the new guy and enjoy the remaining four Tennant specials this year.

That being said I'm also a little disappointed with the choice. Out of the three actors that were in the running, I really wanted Chiwetel Ejiofor to get the role. He's been great in everything that I've seen him in and he already has major sci-fi cred with his roles in Serenity and Children of Men. But hey, the next regeneration is sure to come. I still might get my Doctor.
