I've read the Graphic Novel and watched this movie and both are poorly done despite having great potential. The movie suffers mainly from sparse, unnatural dialog that is also excruciatingly uninteresting plus an almost total lack of a thematic audio track; worse still, much of the dialog is annoyingly echoey. As far as the acting goes, the main character never makes herself believable as a crazy person; Eliza Dushku, as much as I loved her as Faith in Buffy, was totally miscast as a no-nonsense medical professional in this movie; Gina Gershon was entirely underutilized. Overall, I'd like to see this movie picked up by a better production team and made into the great movie it could be. Its main strength was its presentation of the disassociative personality disorder of the main character and her descent into madness and insanity. As it stands right now, I'd recommend the Graphic Novel over the movie mainly because it will take a lot less of your time.
