american psycho was a brilliant book and the film didn't do it justice
the whole novel tries to create a sense of entrapment...hence the beginning is "abandon all hope ye who enter here" and the end is "this is not an exit"
it shows the futility of bateman's situation...
i also think that the murders were all in his head and the scene that shows this most prominantly is when he returns to the apartment where he was supposed to have disposed of 2 prostitutes
then again the lack of anything being mentioned about the murders from other peoples perspective might show how batemans psychotic tendencies just detach him from everyone elses reality completely
fans of american psycho should definitely read lunar park which is not long out...it charts the life of bret easton ellis...the writer of american psycho...but he is an entirely fictional version of bret easton ellis...is shows how someone is supposed to be mimicking the patrick bateman murders and how his dead father comes back to haunt him...
the books final few pages are tremendous...brilliant book
