"Vosburgh’s performance as Carson is disturbing and twisted. She is clearly a talented actress and does not shy away from approaching a complicated role. Her ability to transition from eerily catatonic and blissfully stoned to relentlessly violent and horrifyingly evil is quite remarkable. Coupled with Grossman’s direction, together they turn what would otherwise be an ordinary film into something distinct. Vosburgh brilliantly embodies the intended metaphor of possession as mental illness and the necessary escape that drug abuse provides her."
