I have to admit that my intense dislike of James Cordon on a general level ruins this episode for me. If they'd had any other actor playing Craig I suspect I would have enjoyed seeing Matt Smith goofing around and trying to fit in as a human. As it is, I tend to avoid this ep entirely unless I'm having a *complete* series rewatch from beginning to end. Same goes for the one in the next series when he comes back.

It's a shame, really, because apart from the presence of James Cordon, I have no real complaint about this episode. :-( And also, the technology appears to be Silence tech, so it's quietly seeding plot for the next series.
