In Woody Allen’s latest, Abe Lucas (Joaquin Phoenix) arrives as a philosophy professor at a small New England college. He’s preceded by a reputation as a thinker, drinker, and womanizer, and soon students are flocking to his lectures and women are laying siege to his bed. One is Rita (Parker Posey), a dissatisfied married professor. Another is Jill (Emma Stone), a bright, saucer-eyed undergraduate. Abe has lost his lust for life, and for lust, but it’s rekindled when he and Jill overhear a conversation that inspires him to undertake a fateful, existential action. Allen’s scenes neatly lay out the issues, but you are always aware of the armature beneath them. But like most of this director’s work, it’s intelligent entertainment of an above-average stripe. Rated R. 96 minutes. Regal DeVargas.
