Inherent Vice
Have been fascinated with Thomas Pynchon. He wrote the novel in 2009, the film adaption came out in 2014. It's partially about hippies in the early 70s, but they're insignificant in their own story. The movie is culture, people, and decay, pretending to be about a mystery. The plot exists to move you through a dying world.
The protagonist isn't a hero and isn't especially competent. He's a good guy, with a good heart, and he's too soft for what the world is becoming. The world moved past him, he hasn't realized it yet. Pynchon likes him, but he's not going to let him win. Everything around him has sold out or is in the process of it. What hurts the most is that while this is occuring, the language around him is endless talk of love, progress, connection. While the opposite unfolds in reality.
His drug paranoia, while appearing like madness - is a neccessary survival trait. Shadow orgs move around in the background. They enforce culture, and disappear without accountability. As an allegory for the modern world; moral posturing, censorship for your own good, increasing atomization, and loss of humanity.
