I finished it

Anticlimactic.

I know since there was no real plot there would be no real closure for the ending.
I am also sort of confused. The book is supposed to be satirical, making fun of the yuppie culture while being horrifying at the same time. Most people miss the humor in it though and only see the insane amounts of violent gore.

The main character is rich, obsessed with brand names and being perfect. He is pretty much the yuppie dream, even lives in the same building as Tom Cruise. He's got a steady girlfriend and many others on the side, is independently wealthy but works as a stock broker or some thing, I don't remember it clarifying what.
He just has this one little problem of violently and horrifically killing (and eating) people and animals.

Normally, this is something I would eat up, but I found it to be poorly written and really just annoying. I had to force myself through it. I like Patrick Bateman.He's insane so of course I like him. What I don't like is his stupid need to focus on, and list, everything. He list what he's wearing, what it's made of, the designer and the cost. He lists what everyone else is wearing. He list what they are all eating, how it's prepared, how much it cost, where they are eating. *slamsheadintotable*

BBBAAAH! I kid you not, that is all the book is. Patricks nonstop dialogue of clothing and things, randomly interjected with bouts of insanity and violence. That's it. No ups or downs or plot twists or even a plot really!

I know the point of the book is to make fun of, and point out, the obsession we as people have with things and money. The yuppies in the book are constantly getting each other confused because they are too busy looking at what they're wearing,eating, buying, etc. to realize who they are talking to.

Then of course there's a tiny little hint that Patrick could be dreaming all of it. THIS DOES NOT MAKE A GOOD BOOK!
I DEMAND PLOT! I DEMAND CONFLICT! I DEMAND A BOOK THAT IS NOT 80% LISTING OF CRAP I DON'T CARE ABOUT!
I enjoyed the books violent scenes and subtle humor, but I didn't enjoy the book.
But we all know I enjoy disturbing things so what a surprise that I laughed hysterically at the image of a man, in an Armani suit, crouched over the decapitated and mangled corpse of a prostitute, eating ropes of intestines like noodles.
Really, is anyone surprised?
The book I picked the instant I finished American Psycho? Drawing Blood, by Poppy Z. Brite. Have I enjoyed it? Oh god yes. Give me, my gay boy serial killers making love in a haunted house and I will be content.
Welcome to my romance novel.
