In this sharp, effervescent romantic comedy, Greta Gerwig plays a dissertating graduate student getting ready to settle into married life, until her fiancé's commitment-phobia ruins her best laid plans. Single again and approaching 30, she finds solace in a lovesick platonic male friend and a potty-mouthed sidekick. The stellar supporting cast includes Bill Pullman and Debra Winger as the heroine's free-spirited parents.
