After a long wait - let's face it, just four episodes in 2009 was insufficient - the Doctor is back. A new theme/intro, a new logo, a new producer, a new face, a new companion, a new TARDIS, even a new sonic screwdriver, and yet, so many references to the past. This blend of old and new looks very, very promising. For a first episode, this is up there with the best. Better than Eccleston's or Tennant's. Bring it on, I say.
