The smarmiest aspects of Southern American Protestantism surface in this embarrassingly sincere sermon on the sanctity of matrimony. Caleb (Cameron), a porn-addicted fireman, loses grasp of his marriage to a hospital publicist (Bethea), who similarly lusts after her colleague. Caleb’s “godly” father sends him a “love diary” with instructions on how to win back his wife. The film will no doubt connect with its base, even though it’s utterly uncinematic; this tediously edifying exercise feels exactly like an extended dramatization from The 700 Club. That most of these actors are first-timers (Cameron excluded) really drags this one down in flames.
