Defending Your Life (1991)

Yuppie Daniel Miller is killed in a car accident and goes to Judgment City, a waiting room for the afterlife. During the day, he must prove in a courtroom-style process that he successfully overcame his fears (a hard task, given the pitiful life we are shown); at night, he falls in love with Julia, the only other young person in town. Nights are a time of hedonistic pleasure, since you can (for instance) eat all you want without getting fat.
