"Mr. Anderson’s movie is staged as a talking-head culture-war skirmish between embattled upholders of propriety (or repression, if you prefer) and proponents of free expression (or filth), but its real lesson is that the two sides depend upon each other. Or rather, that the continued vitality of the word — its unique ability to convey emphasis, relieve stress, shock grown-ups and function as adverb, noun, verb, intensifier and what linguists call 'infix' — rests on its ability to mark an edge between the permissible and the profane."
