Saw the film a while back, and read the book a month or so ago, which was incredible.
As for everyone not being able to recognise anyone, i thought that was just about that everyone looked the same! (ie. they're all
suits with designer everything). When Bateman was
pretending to be Marcus Halberstam (sp?), 'cause Paul Owen thought it was him, was very amusing.
I generally enjoyed the observational quotes/comments/thoughts. I think Bateman must've had a obsessive compulsive disorder, as every chapter he'd tell us about the Patty Winters show and also a description of clothing/labels, of pretty much everyone he'd come in contact with. Lots of good quotes as well. Definitley a black comedy, but i felt bad laughing at some of the stuff
eg. the whole episode at the zoo, with the kid and tossing the coins in the seals/dolphins tank
anyway, flamingdog covered lots of good points, it's generally left with a degree of ambiguity so you get whatever you think out of it.
