Let outsiders judge our culture based solely on the films playing on airplanes and they might assume America is made up entirely of 14-year-old girls. But even though the choices for in-flight movies can seem phenomenally boring (now playing on a 17-inch screen shared by 20 people at an airline near you: "Hitch," "Fever Pitch" and "Miss Congeniality 2: Armed and Fabulous"), there's something comfortably numbing about the medium.
