I am suspicious of unifying theories which try to explain the relationship between popular culture and politics. However, A.O. Scott's piece in the New York Times on the defining Hollywood films of the Obama era is pretty compelling:
Last year in The New York Review of Books the critic J. Hoberman wondered when we would see an “Obama-inflected Hollywood cinema.” “The longing for Obama (or an Obama),” he wrote, “can be found in two prescient 2008 movies,” citing “Wall-E” and “Milk” as releases about creative community organizers, with Harvey Milk also a political symbol of hope. It may be too soon to identify an Obama Cinema, but the president’s second inauguration seems like an appropriate time to try.Film is one of the sites where societies negotiate meaning, develop and challenge their own mythologies, and express the hopes, anxieties, and feelings of the collective subconscious. Films talk to us, talk to each other, all the while revealing the "spirit of the age." In total, popular culture is an informal type of public opinion, a barometer for the attitudes of a given society.
Obama's election in 2004 was supposed to usher in postracial America. It did not. Hope and change was met by the twin realities of a coordinated assault on the legitimacy of the country's first black President, as well as how practical governance is an exercise in realpolitik. As such, hope and change had to be surrendered to practical realities--here Obama's right-leaning centrism was greeted by upset on the part of Progressives, and recast as treason and Socialist-Communist-anti-white tyranny by Conservatives.
How do the Hollywood movies made in the Age of Obama reflect these dynamics?
