Original and interesting. Melanie is actually really good here (unlike her entire career after "Working Girl" when she begins think that she has real talent). Nice performance by Daniels as the average square.
Leonard Maltin/Plot synopsis:
Straight-arrow businessman Daniels goes for a joyride with a flaky, sexy girl he chances to meet, and in the course of a couple of days she turns his life inside out. Many surprising twists and turns as this film veers from kooky comedy to violent melodrama, but end result isn't satisfying, especially with tacked-on happy ending. Filmmakers John Waters and John Sayles have amusing cameos as a used-car salesman and a motorcycle cop, respectively.
