“Civilization” takes us on a satirical romp through corruption, consumption, and success in the changing America of 2008. A series of vivid character portraits follows a bipolar waitress and her would-be celebrity daughter, a couple of aspiring self-help gurus, a commercial director with an interest in astronomy, a comedian hiding a suicide attempt, and a factory farm hog planning his escape. Who sinks and who swims in this dissection of the ever-weirder American Dream?
