Girls in a haunted dance academy are dying or being murdered in alarming numbers in this carefully calibrated movie by Simon Barret. When a student in Edelvine academy apparently commits suicide by jumping out her window after a prank gone bad, her replacement Suki Waterhouse is plagued by ghostly sightings. The girls conduct a seance and a ghostly presence emerges. Pretty soon, the body count starts climbing. Pic seems slack on the atmosphere and chills, despite it's "suspiria" inspired setting. Suki Waterhouse gives a sly performance (all deadpan line deliveries) , and the dreamy synth like score adds to the odd, off-kilter atmosphere. But viewers patient enough to sit this through will be rewarded by a great ending - when everything finally makes sense, especially Ms Waterhouse's cool performance.
