Okay, everyone knows the movie.
Not everyone knows the movie was a book. The afterword in the book confirms this.
I had read recently about how Palahniuk's financial advisors had pretty much swindled him out of his earnings from this book ($6000 advance, according to the afterword!), and that, well, he had taken a startling Classical Stoic view on the whole thing. Maybe my purchasing of the book (twice, actually, to my surprise) will help in some small way.
So, this book.
The Narrator is living a typical American life, everything is normal, and he feels empty. He starts going to support groups to feel alive.
I loved the support groups so much, if people thought you were dying, they gave you their full attention. If this might be the last time they saw you, they really saw you. Everything else about their checkbook balance and radio songs and messy hair went out the window. You had their full attention. People listened instead of just waiting for their turn to speak. And when they spoke, they weren’t telling you a story. When the two of you talked, you were building something, and afterward you were both different than before.
Eventually he meets up with Tyler Durden, who is pretty much the asshole every guy wants permission to be. The narrator's life begins to unravel. Said narrator doesn't care much, because Tyler is there to carry him along.
I had seen the movie, I know how the story goes. I had the eight rules of fight club (all lowercase in the book, unlike the uppercase the media uses) memorized at one time. Having now read the book, I am impressed with how closely the movie is to the book. The more subtle details such as the single porn movie frame being spliced into a family movie translated into the movie really well, I can appreciate those details.
