Query: Decidedly mediocre

I'm a big fan of the new Doctor Who series. This episode was not one of the best; in fact it was decidedly mediocre. Make no mistake about it, at 60 mins, this is an episode and not a movie.Opening with a scene stolen from Mission Impossible, and laboring under more pseudo-scientific mumbo-jumbo than usual, the Doctor is given none of usual opportunities to showcase his wit and enthusiasm. About the only thing going for this episode is the interesting image of a red double-decker bus in the desert and a fairly cool alien monster. Our family actually found the behind the scenes documentary of how they got the bus into the Dubai desert more exciting than the episode itself.
