4 stars out of 5 -- "[T]he film's combination of raw performances, unobtrusive, over-the-shoulder cinematography and unflinching darkness will snare even the strong-stomached like snake food."
Total Film

"Throughout Kurzel sustains a mood that's both oppressive and contemplative....This is a well-made, truly sobering film..."
Sight and Sound

3.5 stars out of 4 -- "The film is a chilling study of an evil, dominant personality and his victims. It works primarily through an astonishingly good performance by Daniel Henshall as Bunting."
Chicago Sun-Times

"[The film] builds into a multipronged horror effort....The film is unflinching, but doesn't sensationalize its content, which makes it all the more disturbing."
