American Psycho 2: All-American Girl (2002)

American Psycho, based on the 1991 novel by Bret Easton Ellis, was often considered unfilmable due its mix of graphic violence and esoteric humor — until Mary Harron cracked it magnificently with her outstanding film adaption in 2000.

Two years later, distributor Lions Gate cheapened the original film with this baffling film starring Mila Kunis and William Shatner. Abandoning all the social satire of American Psycho, the film stars with a young girl murdering Bateman, and subsequently becoming a killer herself. Unsurprisingly, it was based on a script that initially had nothing to do with American Psycho, but was misguidedly linked to it to capitalize on the success of the Mary Harron film.

Don’t blame Kunis, who has expressed regrets:  “When I did the second one, I didn’t know it would be American Psycho II,” she told MTV News. “It was supposed to be a different project, and it was re-edited, but, ooh … I don’t know. Bad.”
