Consider the following: Batman Begins, The Dark Knight, the Spider-Man franchise, both Fantastic Four movies, Hulk, The Incredible Hulk, Transformers, 300, Ghost Rider, and the new Iron Man movie.
In the last five years we've seen an explosion of superhero-based film (not to mention heroe-esque TV fare). What all these movies have in common, besides silly underwear and big box office returns, is an easily-digestible good vs. evil dichotomy.
Some observers would call our obsession with heroes a form of escapism during a time of societal tension. And while I'm inclined to share that view, it's worth noting that the simplistic dualities of our imaginary worlds are at the barest remove from the simplistic dualities espoused by our real-world leaders. Consider the "with us or against us" cowboy-isms of George Bush, the charisma-heavy, experience-light platform of Barack Obama, or the 12 commitments of Rudy Giuliani, which boil down to "a leader should lead regardless of what the people say."
All of this is simply to say that our reality is becoming its own form of escapism, repeating back to us the platitudes we're accustomed to consuming in the theater. I'm not a fan.
