Like it or not, Zack Snyder‘s Batman vs. Superman (Warner Bros., 7.15) will star Ben Affleck as Bruce Wayne/Batman and Henry Cavill as Superman. But lost in the Batfleck hubbub is a question of basic plot dynamics. The title indicates the superheroes at cross purposes, but what kind of misunderstanding could result in these Dudley Do-Rights going up against each other? (The Superman-Batman comic book series, launched in ’03, “explored the camaraderie, antagonism, and friendship between its titular characters,” says one description.) And what kind of mano e mano tension can result from a mortal crimefighter duking it out with an extra-terrestrial with super-powers? One presumes that David S. Goyer‘s script will divest Superman of his spectacularness.
