First and foremost, another 2 thumbs up for Jericho. Main characters actually died, and it covered many situations that we would hope never happen between Americans. Oh, and there were several pretenders to the throne of the Presidency, one of which was backed by the megacorp that may have had something to do with the underlying plot.

Firefly, while set 500 years from now in another star system has a gritty "just tryin' to get by" feeling. Survival by dealing with less-than-honorable clients, evading the military government of the area of operation, smuggling/trade--lots of good plot fodder.

While I never watched it, "Jeremiah" dealt with a PA scenario where a bioagent wiped out nearly all the adult population.
