It's a weird conceptual movie, but "Happiness." It's about 3 sisters who live different types of life. A 30 year old struggling to find her way. Her sister who is married to a husband who is attracted to children, and a woman who has a successful life, has all the sex she wants with attractive guys, but isn't satisfied per say. It's hard to explain without giving the entire movie away.

It's a pretty good movie tho.
