Apocalyptic Dystopia 2009

I have noticed that there are a lot of dystopian Apocalyptic movies being released in 2009.
2012, The Book of Eli, Carriers , Daybreakers , Knowing , Gamer , The Road, Legion , Surrogates and Zombieland and that’s just to name the soon to be released one’s. For movies to be this depressing indicates that they were being created in the latter part of the Bush/Cheney Era, when the world was very depressing.
