In terms of the story-line, the film and book are quite similar. Most of the differences deal with how, Patrick Bateman (Main character) feels internally. There are parts in the book that just wouldn’t work for film, in order to avoid an NC-17 rating. The film is very much less explicit than the book is the sense that more of Bateman’s insane inner thoughts are revealed in the book. The book has much more graphically violent and sexual content. The violence in the book is actually hard to read at times. In the film, the narrative feels more like a black comedy. Take for instance, the scene where, Bateman is having a threesome with two prostitutes and while doing so he’s looking at himself in the mirror and giving himself a thumbs up. The book is made to be funny in a clever way, but unless you have a morbid sense of humor the film was made to achieve more of an appreciation for the overall theme of the narrative. On the other hand, the film does a good job of painting a picture of Patrick Bateman as a narcissistic and abrasive madman that only cares about material possessions, restaurants, raping and pillaging. In the book hes still a serial killer, but he doesn’t rape any of the women he kills , but as mentioned prior he does partake in extremely graphic violence. The character traits in the film are very disturbing, but there are also many components about Patrick batman that make him likable-like when he voices his opinion on Sri Lanka and world hunger-stating a case for positive priorities -during a dinner scene, but Im sure the rating angle played a major role in the content that was omitted for the shooting script, rather than the filmmakers trying to make Patrick Bateman a redeemable character. Still I feel the film is better than the novel.
