though I don’t really remember “Catcher in the Rye”.
I love “Fight Club”, book and movie. It says so much about how distanced we are from anything real.
I don’t think that it will become the anthem of serial killers, because at the bottom, it is more a book about seeking life and connection and meaning than it is about anarchy and disconnection.
The first real move away from disconnection was when Bob is killed. He actually feels that, and cares. Then, the reality of what he is doing sinks in, and he starts to see the truth about his dual nature, and starts to mend the gap between his two sides.
I always found it to be about Tyler starting off being disconnected, but growing towards connection. After all, he reconnects with both sides of himself and reconciles them in the end. The end of the movie actually feels like the beginning of his real life for me.
It is totally possible that disturbed people would only focus on the anarchy and disconnection.
