A bit of Welsh nastiness from Marc Evans, shot in Nova Scotia with American actors. A snowbound house, five "slices of white bread" coming to the end of their tenacy in a Big Brother-inspired, web-cam surveilled spooky house. After six months, they are a few days away from the million dollar prize until bad things start to happen. The film lays on suspense and tension through a soundtrack of electronic whirrings and clicks, toys with us with a paranoia-upping visit from a stranger, and ends with a satisfying bloody third act. There are missteps--Evans betrays his handicam-only aesthetic when he tries to make the kills zippy, and it's never really feels like these five have been living together for six months. But it has a dark and despairing ending that Stephen King would love.
