The film is symbolic for a disease

Rating: 8/10 (23 January 2006)

Marla is symbolic for - depression Cornelius (or whatever his namne is) is symbolic for - normal And Tyler Durden is symbolic for - high mood A person with "bipolar disorder" have all these three personalitys. They can be depressed, normal and extreme self confident about themselves. They don't care about small things and have grand ideas when they are in a high mood (Tyler durden) When the buildings fall down in the end of the movie it's symbolic for what the disease has done to him, and he will fall down into a low mood. He is standing there and holding hands with Marla which stands for depression.
I'm almost positive that the film is symbolic for something like this
