Director Alexandre Aja’s latest film — Piranha 3D features a man getting his penis bitten off by killer fish. And that’s a major Hollywood film. So one has to expect far worse, in terms of violence, from his earlier stuff. He doesn’t disappoint. Director of the remake of Wes Craven’s disturbing family-in-peril film The Hills Have Eyes, Aja preceded that by three years with this French horror flick about a girl who witnesses the slaughter of her friend’s family while staying at their home. There are a lot of sharp objects in this film (knives, axes, chainsaws), and they’re all used in very effective ways. Yet for all the violence, it’s the film’s unforgettable ending that leaves the audience feeling most violated.
