"Batman is a superhero without superpowers. He is one of us. Human. Flawed. But as the movie suggests his enduring appeal is that of a noble idea: that one man can make a difference and be a force for good in the world."
"What separates Batman from other superheroes -- and what the movie conveys -- is that his mystique taps into our fears and sense of helplessness. And while he is after all just a comic-book character, the film's archetypal image of Batman standing solitary vigil on a rooftop turret speaks to our deep desire for protection against life's uncertainties."
"For me, Batman has an enduring appeal and endless fascination because he is a relatable character. He is referred to as a superhero, but actually he is a self-invented superhero. And I think the fantasy of a man who, through sheer will and self-discipline, has turned himself into more than just a man, into a heroic figure…that's just a very compelling myth."

"All I can think is that this relentlessly dark and nihilistic film is tapping into the American Zeitgeist, confirming our society’s misery in the face of an endless war in Iraq, housing prices up, gas prices up, food prices up, economy stalled, health care a mess, having to face the reality that our government condones torture, etc. etc.) Americans feel like victims of forces far beyond their control, as do the citizens of Gotham at the hands of the Joker."
