All over the place. Starts off dramatically in a boys prison, before becoming a goofy chav version of The Most Dangerous Game. Some acting is strong, it can be funny in a sick sort of way, but the characters are poorly defined or non-existent so there's nothing to engage with. The slasher bits are few and feel out of place, with only one effective kill. Overall it's lazy, with shots of trained German Shepard dogs running in a field being a good portion of the "action".

A lean and mean 94 minutes of animal attack horror that descends into a brutal backwoods nightmare that is completely unexpected. The backwoods dread feels very real in this one. The menace and terror are captured unbelievably well and the isolated setting made for an ideal horror film. All the deaths and traps are simply excellent. Consistently rock-solid performances and a great atmosphere, also filled with a lot of action and more than enough gore to satisfy just about any gore enthusiast, you have a film that never fails to grip the attention. That one guy and the dogs truly deliver a coldblooded, menacing, and unforgettable villain.
