The movie critic reviews Non-stop, and finds it lacking. Nonstop is the story of a flight from New York to London with a terrorist and federal air Marshall on board. The intent of the film makers is to draw the audience in by developing several characters among the passengers and have the audience try to figure out who the terrorist is.  Is it the cop traveling to see his sister? The Arab? The flight attendant? The chatty passenger? The pilot? The air Marshall himself? The better question is who cares?
