If “war is hell,” then every soldier is a sinner. It would be nice to think that every American who fought in World War II was a saint, but we know that’s not the truth. War makes monsters because it has to, and we have to live with that ugliness because it’s in service of defeating a greater evil. Since we as Americans accept without question that Nazis are evil and deserved to be killed en masse, writer-director David Ayer turns the problem of morality towards American soldiers with his new movie, Fury. Despite strong central performances from Brad Pitt and Logan Lerman, Ayer’s picture ultimately feels hollow as the spectacular action and stomach-churning violence never take us anywhere beyond what we already know: war is hell.
