I'm not sure why this movie is unpopular. I laughed out loud. At first I thought "Oh what a cute little movie" until the moment Whitman lets his guard down. Then it just gets out there. Joan Cusack (or "Joanie Baby" as we call her) is hilarious. My favorite scene: The sisters reaction to each other when Martha describes her first date with Whitman. I love this movie, and I'm usually pretty picky. In a way, it reminds me of After Hours, just not as dark.
