6.25 of 10. Are they roommates or just 2 versions of the same person happening within a psychotic aspiring model with a tendency to binge on eating, sex, and self abuse? Either way, you get 2 similar looking actresses, a slender model and a plump mess, playing the lead rolls.
As simply horror and gore, it doesn't pick up until the latter part of the film. The first half is essentially dedicated to setting up the characters and their/her various disorders/psychoses. That does set up a mystery angle to it and make the film more enjoyable and less predictable as to where it's going.
It's rare to get so much character depth, plot, gross-out scenes, horror, and hot ass shots in the same film. Worth a watch even though it makes a mistake at the end with not really completing the story and going with more of a setup for a sequel.
