The one movie and book that had the biggest impact on my life was Fight Club. It not only shaped many of my beliefs about society, but even had an impact on some of my friendships as I was growing up, for better or worse.
It did not introduce me to a lot of concepts or ideas that I had never considered, but more that it presented those concepts as a game to be played and as real life with consequences simultaneously. Because of this it was incredibly dark/sad as well as funny/inspiring. It was fun to make-believe that you were going to start a revolution to overturn consumerist culture and globalist apathy, and it was also scary the more you pushed those concepts.
Over 20 years later, it feels incredibly relevant now.

Is your life so empty that you honestly can't think of a better way to spend these moments? Or are you so impressed with authority that you give respect and credence to all that claim it? Do you read everything you're supposed to read? Do you think every thing you're supposed to think? Buy what you're told to want? Get out of your apartment. Meet a member of the opposite sex. Stop the excessive shopping and masturbation. Quit your job. Start a fight. Prove you're alive. If you don't claim your humanity you will become a statistic. You have been warned."
