For those who think the film is awful...
First of all, no, the film wasn't tremendously statisfying dramatically. It's a 75 minute, nonlinear, digital film shot in a couple weeks starring an actress who had only done porn up until then. You were expecting Hamlet? It's not like all this information wasn't already out there. This was pretty clearly an experimental film on many levels... seems like people would be willing to go with it.
Having said that, it is not at all dumb and certainly not pointless. Soderbergh even holds your hand by placing all the key themes explicitly in the final scene.
On the surface the film is a look at a type of lifestyle that is shallow, stressful, and unfulfilling. A world where everything is a commodity.
But underneath that the film is also about the anxieties of modern life. It's about captial A Angst. The main characters are searching for something better. Better job. More control. Someone they have more of a connection with. Some sort of spiritual or philosophical answers. They're constantly on the go and trying to evaluate their lives, but nothing seems to bring them any closer to peace or contentment.
As I said, it's all there in the final scene. A practicing Jew worried about the economy and the state of Israel hires Christine, but not for sex. He hires her to hold him... to comfort him. Everything troubling the characters in the film is emobodied by this one guy: society, politics, economics, sex, religion. The whole package. It's enough to give a guy the shakes.
It's less a story, or even a portrait, as it is a sign of the times.
