I watched the first episode but missed the second -- curses! -- which I hope to rectify soon. I enjoyed the first one, and the characters in it are rather engaging. The mouthy Irish one is a bit too mouthy at the moment, but I really liked the chav...sorry, the girl who's not a chav, don't keep calling her that. I cottoned onto the fact that their 'powers' were all to do with what they're 'socially' like, as it were before we had the little section that pointed this out (like the athlete rewinding the tapes of him).
Certainly looks to be an interesting programme. I rather liked how abrupt and unexplained (and styalised, with the slow-motion and the lightning) the 'event' thing was.
