"Director Alexandre Aja manages to create one of the most layered and suspenseful slasher films ever made since "Halloween" and while displaying often disturbing scenes of graphic violence, the film's main point is its atmosphere and tension as these two people play a game of cat and mouse trying to outwit one another relentlessly. The film continuously runs on a loop of a pretty plot-less and utter pointless violence and gore which becomes an exercise in snuff and brutality that didn't satisfy any need I had for a true horror movie." - Felix Vasquez Jr., Cinema Crazed
