Finally, the fourth Dr Who series comes to an &; and it is surely Davies's wish to fly out on an ampersand. Still, Tennant rescued a potentially mawkish episode that spent too much time tying narrative shoelaces, and played whoops apocalypse a little too easily. Can Davies climax? Not this time, apparently.
Two thirds through, I thought that I was transported to Return of the King, where the battle is over and everyone spends an eternity saying farewell. Only with Donna's sacrifice, after the alkaline Maguffin of heroine, and the existenz of the ninth doctor's darkness, did the end redeem itself.
Torchwood recruits trailed and Rose's happy ending wrapped up all. Only poor Donna is left with true tragedy, as all that is gained is lost. And, as the final trailer sloughed past my vision, a hapless hobgoblin bleated: "New villains please!".
