Movies about the end of civilization have been in vogue since at least the late 1990s. There have been movies about doom coming from the skies like with Deep Impact and Armageddon, viruses ravaging mankind like I Am Legend and Contagion but it seems like the most popular of the apocalyptic movies have been about alien invasions like The War of the Worlds and Independence Day. And while films like these can do a great job of depicting events leading up to the end of things, the limited scope of movies means that they tend to focus on the spectacle of things going “bang” during the apocalypse rather than having the time to deal with any in-depth story of what comes after.
While movies might not be good at in-depth stories TV series are, and one of my favorite of these is the post-apocalyptic series is Falling Skies on TNT.
