In almost every way, this 3-hour-and-35-minute prequel to 1993's Gettysburg, starring Robert Duvall as Robert E. Lee and Stephen Lang as Thomas ''Stonewall'' Jackson, is a trial to sit through: stiff, ponderous, fluttering, and crudely simplistic as an apologia for the Confederate ideology. It would be nice to say that the battles are powerful, but instead they are draped in Civil War-buff ''authenticity'' without so much as a drop of carnage.
