Remember when we used to debate who was the better Batman? Clooney? Keaton? Ummm, Kilmer? And then, in 2005, came the Dark Knight trilogy, with “Batman Begins.” Bankable, big-name stars can make for good box office, but it’s the story that makes for a great movie. When Christopher Nolan rebooted the Caped Crusader, he made the story less like the cartoonish 1960s TV series and more like the brooding comic books. And he surrounded a relative B-lister, Christian Bale, with stellar cast of character actors. Because if the story’s good enough, Batman is the only bankable big name you need.
