I also thought it was a promising episode with an incredibly compelling concept, though that bit with the torch at the end did cause my brain to leave the building and wait for it all to be over.

Hmmm, interesting that the ep should be so very much about the ways in which love can be a trap -- the Chloe and her mom clearly refugees from a horribly violent dometic situation, and the weirdly vampiristic hunger of the being who needed so much love to survive. The show has been doing a great deal to explore the Doctor's emotional bonds or lack thereof -- it's interesting we should get the casual confession that he's been a dad in the context of a show in which love is so . . . overwhelmingly dangerous?

Hmmm. Very interesting show.
