The Christmas specials - it still feels nice to say that at all! - get back on form with The Next Doctor, a neat mix of mystery, running around, smashing things up, and neat little character pieces as we slowly reveal just who this character who appears to be a future regeneration of the Doctor actually is. There's lot of hints that you'll probably not pick up on at a first viewing - there's decent depth here, of both story and character, while also being rather good fun, and it breaks from what was quickly becoming an alarming tradition of the last couple of specials by not giving a one-shot companion who the Doctor ends up rather liking. The Cybermen are never exactly my favourite monsters, but I don't mind them here as they're pretty incidental to the character stuff going on.
Atmospheric, touching, and with a reasonably tight storyline, this is easily the best of the Christmas specials since the first, and far more consistently strong than that one (the first isn't exactly consistent all the way through, but the last 20 minutes make up for the all the uneven tone of the rest). Very good indeed.
