To be honest I think it also depends what market they are chasing. Most TV SF being produced at the moment is chasing either the Dr Who or Torchwood audience and I can't imagine this idea being handled intelligently for either of those audiences (especially not the Torchwood one) or, in fact, for any ITV audience. In fact gominokouhai's reference to that "last man on Earth" comic just makes me think depressed thoughts about a Torchwood "sexed-up" style version of the story in which a Mary Sue for the author/production exec turns out to be the only man capable of solving the problems of numerous infeasibly good-looking women (because, you know, he understands technology and stuff) who proceed to throw themselves at him (that's when they aren't having hot lesbian sex). If it was being made for BBC 4 I might have some hope but being made for ITV? I just can't see it.

Maybe I'm unnecessarily jaundiced about modern TV.
