‘Hancock’ hero’s feats of clay

In the summer of “Iron Man” and “The Dark Knight,” the decidedly rattier “Hancock” came off as something of an also-ran, though this offbeat adventure was every bit as daring. Will Smith dials back the charm to play a moody superhero whose attempts to save the day always backfire, and Jason Bateman is his typically frazzled self as a corporate do-gooder who tries to save Hancock’s image. Director Peter Berg’s jittery action sequences go a long way toward selling “Hancock’s” critique of how the public treats its heroes. The double-disc DVD and Blu-Ray editions contain a generous complement of featurettes. (Sony)
