Well I have to say that this episode isn't bad it is better that what we have been seeing for the past couple of episodes, but I don't think that it is great by any means, the aliens are not scary they are not menacing They look more like a creature from the second episodes of Torchwood.
I did catch that part where the music with the little girl is from a Slyvester McCoy episode. I also think that you over intellectualize DW from time to time Warren.
