I have learned that “The Adventures of Buckaroo Banzai,” a cult classic, is an acquired taste. I acquired it when a college roommate quoted from it occasionally. But You have to love a movie where: the Defense Department is queried about “the possibility of war in the eighth dimension, Mr. Secretary?”; the President of the United States sputters: “I, uh... I don't know what to say. Lectroids? Planet Ten? Nuclear? Extortion? A girl named John?” and contends with “Declaration of War - the Short Form”
