I Heart Huckabees (2004)

An eco-warrior experiencing a coincidence consults a pair of existential detectives to help him sort it out, but they uncover much more than he bargained for.  I was along for the ride and enjoying it immensely -- but the fun didn't last all the way to the end. Once Isabel Huppert came on the scene as a proponent of meaninglessness (a polar opposite view to the one taken by the detectives), things got more strained than strange.

The cast is completely game and story is warped and fun, but it just needed to figure out when to say when.
