I am currently watching season 1 of a show called Jericho that I bought on dvd.  It is fascinating.  This show came out in 2006 well after 9/11 and the then-recent Blackwater scandal and paints a frightening end-of-the-world picture told from the perspective of the small town of Jericho, Kansas.  I am glued to the show so far, having gone through 3 discs.  It is intense yet sweet at the same time.  So far, highly recommended.
