I quite enjoyed the first episode, though it wasn't a patch on Children of Men, which I thought was really good. In style it rather reminded me of Flashforward (which I rather liked despite its faults), if not - yet - quite so convoluted in plot or with such a large ensemble cast. A lot of the actors seemed to mumble their dialogue in the manner that now seems to have become fashionable, so that I couldn't make out some of it, which annoyed me. (I suppose that could just be my hearing getting worse as I get older.) It was sad to see Rhys and Gwen being quite so paranoid, though it seems that they had good cause.
