Thanks for the help, all. Several of us "linear thinkers" watched the movie last night and none of us made the leap to thinking about the entire movie as a metaphore. All four of us were grasping for at least one concrete thread to ground a story to, but never did find one. I suppose I'm with Jameswei, above. I appreciated the art of the film at a certain level, but felt at the end that I'd wasted my time in watching the whole thing.
