A decent enough slasher film that becomes a really good, fun thriller. A couple celebrating their thirty fifth wedding anniversary invite all their children, together with their relative partners, out to their mansion in the woods to celebrate with them. Unfortunately, someone decides this same group would make excellent target practice for their crossbow. At least, that is all the family have to go on for motive when they suddenly find themselves under attack in their own home and must do whatever they can to survive.
Sharni Vinson does a fantastic job of playing central character Erin, the sexy Australian girlfriend of one of the brothers who turns out to be hard as, ahem, nails, and the rest of the cast do a good job of both creating the right atmosphere and suspense, whilst simultaneously managing the difficult task of getting the audience to laugh with a horror film rather than at it. For fans of the genre this is to be highly recommended.
