I think black pilled might have analyzed this one too. He's great on film analysis.
American Beauty is interesting because it's kind of like purple pilled PUA type stuff... he is disillusioned with his life not being fulfilling despite following society's blueprint, yet his breakthrough only leads him to smoke weed, work out, cease giving a fuck and hit on young women. Halfway there but never making it to spiritual truths, only trading one kind of emptiness for another that provides more dopamine.
Saying he hit on young women is a stretch.
I admit the film is deceiving. If you watch the trailer, you'd swear that it's about some older guy lusting after a girl that's too young for him. Even in the initial scene, where the protagonist is introduced to the girl for the first time, we see that he wants her. And then he's later shown calling her at home to hear her voice. And yet, that is where his lust stops.
The girl suddenly becomes the catalyst for him to change his life to make himself a better man.
After his metamorphosis, his daughter's friend now flirts with him and eventually comes to him to validate her own beauty which she now doubts. If he truly wanted to, he could've slept with her, but he didn't. His motivation was to break free from his middle-aged rut. While that included making changes to his life, it never seems like he intended to cheat on his wife.
I also wouldn't say he traded one emptiness for another. He changed into a better man who instead of walking like a zombie through life, found a way to look at life in a new way and even tried to rekindle his marriage which was on the rocks.
However, just like Falling Down, there is some subversion in this film (strangely enough, this film too involves a character with a secret Nazi room).
But just like the Michael Douglas movie, American Beauty can be both enjoyable and teachable if you take away the parts of the movie that conform to a Christian worldview.
