Yes - I love this movie. Who doesn't? Nearly every person that I've met who works in IBD thinks this is a great movie because it makes investment bankers look bad ass. Even though I love this movie, I think a lot of people have the wrong idea (if you don't and I am stupid, tell me in the comments section).
American Psycho is a comedy - a dark one, but its a comedy. When Christian Bale first saw the script, he laughed and asked if it was a joke. What's the joke? Investment bankers! Patrick Bateman is someone who thinks he should be so important, because he is an investment banker, and, as we all know, investment bankers are masters of the universe. But, nobody can even remember his name, he's nobody. He gets away with a number of murders because even his closest friends and his lawyer have no idea who he even is. He starts killing because he feels like such a loser and is trying to get attention in any way he can.
So, where is the joke here? What makes this funny? Bret Easton Ellis, the book's author, was trying to draw attention to the fact that every single investment banker is exactly the same. He's also trying to say that investment bankers have no reason to feel like such hot shots because none of them are any different from the next, none of them so special.
I can't deny that I think this is a great movie, but I think it's good to always keep it in mind when talking about it. Also, there are a number of ways to interpret this movie - just like everything else this analysis is not "right". If anyone thinks I'm totally off-track here, let me know in the comments. I'm really looking for a discussion on this one.
