At first glance the directing duo of Jen and Sylvia Soska might appear to be little more than a shtick. Twins with jet black hair, wonderfully foul mouths and an affection for the bloody wet stuff, they could easily be mistaken for filmmakers more interested in style than substance. But while their feature debut, Dead Hooker In a Trunk, is a brilliant title in search of a worthwhile film, just three short years later they’ve made a dramatic leap in quality with their sophomore effort. American Mary is part revenge thriller, part black comedy and part body modification training video, and it works hard to tell an original and entertaining story. It’s an odd film destined to stand apart in a genre overrun with ghosts, found footage and masked serial killers, and the fact that it’s anchored by a fantastic female lead performance is just icing on the blood-lined cake.
