American Psycho

Author Ellis said said that while the book attempted to add ambiguity to the events and to Bateman's reliability as a narrator, the film appeared to make them completely literal before confusing the issue at the very end. Ellis indicated that his feelings towards the film were more mixed than negative; he reiterated his opinion that his conception of Bateman as an unreliable narrator did not make an entirely successful transition from page to screen, adding that Bateman's narration was so unreliable that even he, as the author of the book, didn't know if Bateman was honestly describing events that actually happened or if he was lying or even hallucinating.
