I <3 Huckabees: incompleteness There's a lot to talk about, philosophically, in I <3 Huckabees, and I can't say any element stuck out to me as most noteworthy. But I was very interested in the fact taht nearly every character was presented as having a philosophical view that was in some way clearly narrowed by their own biases.
The possible exception to that is Albert, who in the end comes to a philosophy based on the fusion of the detectives' perspective and Caterine's. But even in that case, the philosophy he arrives at is based on the presumption that he'll lose his ability to retain his detached and enlightened perspective.
Overall, the film seemed to imply that no one can have a complete life-philosophy that accounts for all the realities of the human experience. It will either be too nihilistic or too optimistic, too materialist or too detached, and in every case shaped by one's past relationships and experiences in such a way as to warp it.
Caterine and the detectives' extremist philosophies are accounted for by their past relationship with each other. Tommy's reaction against materialist culture has its roots in 9/11, and even then, he focuses narrowly on one specific world problem rather than addressing the whole picture of human suffering (which would, itself, still be incomplete.) Brad seems to be reacting to his brother, and Albert's angst stems from childhood neglect.
The wounds left by human drama in the lives of each of the characters warp their ability to perceive the full spectrum of human experience.
A short note on incorrectness
I don't know whether this was intentional or not, but Bernard, when he's arguing with Tommy about the connection/alienation between particles and cracks in the universe, he says that every atom in our bodies was forged in the furnace of the sun. That's not correct -- the atoms that make up everything on/in earth were forged in the furnace of stars that had exploded long, long before the earth and the sun were formed.
In the same sense that every philosophy is necessarily incomplete, if that was intentional it seems also to imply that a functional though incomplete philosophy can stem from functional but incorrect information.
