How does one stretch a barely 30-page short story of accumulated gripes and grumbles into a feature length film? In the case of "Alexander and the Terrible, Horrible, No Good, Very Bad Day," the answer is simple: poorly. By the time its 82-minute running time comes to a grateful close - and all of the cliché, contrived and crude chaos with it - Alexander's bad day has morphed into the audience's bad day.
