I saw I <3 Huckabees, and it was just great.
Essentially, it is about
people who enlist existential philosophers to be therapists who consult based not only on information gathered in therapy sessions, but also base on information gather through detective work. You hire them, they spy on you, interview you, and then consult you on the nature of the universe.
Basically, the movie pokes a little fun at people who take philosophy way to seriously. It's kind of absurdest, and was just hilarious. Although I doubt anyone who doesn't enjoy philosophy would enjoy the movie.
