Has any show with a similar theme survived more than one season? Jericho made it two seasons, but those weren't full seasons.
It should be interesting to see how Revolution does. It's not post-nuke (at least, not that we're aware of at present), but it is certainly a post-apocalyptic environment, replete with the usual bevy of mystery and conspiracy with a bit of sci-fi thrown into the mix. I wouldn't say it's the same, but their are some similarities.
