Catharsis for a cubicle nation. Writer-director Mike Judge (MTV’s “Beavis and Butt-Head”) comically chronicles the banal details, petty frustrations and overall soul-crushing inanity of working for and with morons in a meaningless corporate job. In other words, he’s captured the existence of millions of Americans. By deflating the misplaced sense of self-importance that often comes with a white collar, Judge has made working in such an environment a little more bearable. (How many agonizingly slow Wednesdays have been leavened by an Office Space reference shared among coworkers?) With Ron Livingston, Jennifer Aniston, Gary Cole and Stephen Root, though the cast is almost arbitrary. The movie’s scathing bitterness is the star.
