Doctor Who 2008 episode 7

Well, at least it was better than the last episode. The first two thirds were even really fun and, though silly as hell, delivered with verve. But -as I tend to say quite often- Doctor Who could really use a good story editor, at least one good enough to see that it is one thing to play with the style of this year's author who meets the Doctor, but quite another to copy all the faults this author's plots have. Since the show doesn't have one, the last act is plagued by everything that makes Agatha Christie's books so loathworthy - a solution to the murder mystery that manages to be obvious and deeply stupid at once, characters acting like cardboard cutouts and the pacing of a dead snail.
And please, dear, dear writer - do not try to explain Agatha Christie's fame by her ability to deeply understand people's passions and acts. Her books did never more than reproduce the social values of her time, which is as far from understanding people as is possible.
