Well here is an interpretation of The Dark Knight that passed over my head
There seems to me no question that the Batman film "The Dark Knight," currently breaking every box office record in history, is at some level a paean of praise to the fortitude and moral courage that has been shown by George W. Bush in this time of terror and war. Like W, Batman is vilified and despised for confronting terrorists in the only terms they understand. Like W, Batman sometimes has to push the boundaries of civil rights to deal with an emergency, certain that he will re-establish those boundaries when the emergency is past.
And like W, Batman understands that there is no moral equivalence between a free society -- in which people sometimes make the wrong choices -- and a criminal sect bent on destruction. The former must be cherished even in its moments of folly; the latter must be hounded to the gates of Hell.
"The Dark Knight," then, is a conservative movie about the war on terror.
I see the Gitmo/"enhanced interrogation" issues when Batman "questions" Joker in the holding cell and listening in on every cell phone conversation in Gotham was a clear reference to the monitoring of telecom communications without approval under FISA, but W as the model for billionaire playboy Bruce Wayne was something I missed - more humor from the WSJ editorial page
