Before long, word of Mary’s talent spreads, and she begins taking on ‘underground’ surgery jobs that are too extreme for legitimate channels. At first, she is quite professional about this new scene, but when Mary is date-raped by a person she thought she could trust, something in her flips, and her vengeful butcher side is released.



The film’s direction by the Soska sisters is impressively restrained; this isn’t an over-the-top gore show. The sisters understand that just the idea of some of these medical procedures is creepier than actually showing them in grisly detail. It’s also even creepier when the end result is shown.



Their writing however, is not yet at the same level. Within the opening minutes of the film, we have a med school professor dropping F-bombs in a lecture and telling Mary “I have enough useless twats in my class”. We get it, you know some swear words, but there’s more to writing interesting dialogue than having your characters say outrageous things. There are also major structural problems, with numerous subplots that go nowhere, and an ending that comes about seemingly because the writers couldn’t figure out how to close the film. Mostly, the problem lies in a lack of focus on any single story element.
