I always worry about medical students. After all, there is a fine line between “I want to cut this guy open and save him” and “I want to cut this guy open and mess around in his bits for shits and giggles“. While both parties might think slicing open the human body is a fun time, I do wonder who gets more out of it, the surgeon who is paid big bucks or the killer who does it just for the enjoyment. The lead character of the Soska Sister's second film, American Mary, walks a number of fine lines, morally, sexually, and professionally over the course of the film. It is the lead character's ability to navigate these split hair differences (for better or worse) that propels the action and this thriller, yes, thriller, toward a blood drenched conclusion. So come with me as I slice my way into the world of underground surgery, body modification, and lots and lots of blood that is American Mary.
