For all its purported shock value circa 2000, both the sex and violence and the satire are toned down quite a bit compared to the book (which makes it less exploitative, which is good, and less disturbing, which is not as good) - though thankfully the tone mostly makes it intact.
This is one of the most dynamic, virtuosic, hilarious, unforgettable screen performances ever. The film itself functions equally well on the levels of character study, social satire, period piece, absurdist slasher farce, and mindfuck psychodrama. Next to the irrepressible Christian Bale, the film's greatest asset might be the female eye behind the camera, lending this study of male vanity and insecurity real bite.
American psycho is a vile and compulsion thriller that make an absolutely satiric portrait of the american's identity society obsessive by esthetics in the depth of their self. A Bateman lives inside everyone of us where narcissism is driven by it's ego and fueled by greed. Lifestyles and business cards are compared in an exceptional personal rivalry but ultimately everything is pointless and there's no catharsis.
The narcissistic thought-processes of a yuppie-douchebag!!! Even though the 80's are over ... some still walk the earth (shudder!) in other forms!!! Those vegan-guys with the Jesus-beards ... THAT'S THEM!!! (Huey Lewis didn't make it though. That's a cryin' shame.)
