Paul Blart: Mall Cop

The title of this farce about an overeager ? security guard (Kevin James) suggests a one-joke trudge. But Paul Blart: Mall Cop has a few ? surprises in store. The biggest is James, an ? unexpectedly nimble master of the face-plant, the failed jump, and the lopsided tumble. The ? former King of Queens star also proves to be a warm leading man who grounds the movie as ?it morphs into a loopy heist thriller after a promising start as something entirely ? different: a gentle comedy of suburban underachievement.
