Tara Subkoff (All Over Me,The Cell) moves behind the camera to write and direct this based-on-true-events cult horror entry for IFC Midnight. After one of the zippiest title sequences in recent memory, six well-heeled twelve-year-old girls settle in for a sleepover in a mansion where “the vortex of the four winds” once converged to drive a former owner to suicide. The subject is cyberbullying, and after a good hour of exchanging insults, the blood begins to flow as the spoiled sextet quickly learn that true horror lies within. Subkoff called in a few celebrity favors from pals Chloë Sevigny, Timothy Hutton, Balthazar Getty, and Natasha Lyonne, all of whom serve the silliness well. What little social commentary there is quickly loses its bite as flashy video game graphics are called upon to supply shocks that lead to an ending that is anything but unexpected.
