I thought the "End of Time" specials were brilliant. I did expect the Doctor to say "don't get cocky, Wilf" during the gun turret scenes though. lol. Bernard Cribbins was as great as ever. It was definitely the best TV show on over Christmas and a great ending to the Tennant years.
I see we are getting some new style Daleks in the new show and the weeping angels are back too and an old style Tardis. The new interior though looks amazing and big (it's built on the old Torchwood hub set so plenty of layers and space)
