It takes a strong stomach to see Annie Hall playing a wanton slut of a woman, left behind by the sexual revolution. Nonetheless, Diane Keaton pulled a 180 in this gritty drama, about a schoolteacher for the deaf who experiments with drugs and (more importantly) wild sex, during the era of free love. Overflowing with symbolism and hopelessly depressing, this one is a true eye-opener. If you think you know Ms. Keaton -- you don't, until you've seen this one.
