There are few tropes as deeply ingrained as those of the horror genre. More often than not, even a luddite could spot a horror film in the first minute. But in a way, this overwrought frame that we have all become so familiar with has pushed many young filmmakers to buck against the cliches and create some truly surprising and downright chilling movies.; last year alone we got “The Wailing,” “The Witch,” “The Invitation,” and “Green Room,” most of which feature at least a semblance of those same well-trodden narrative devices and archetypal characters. Basically, there is hope that even with the most familiar set up, a film can still transcend into a worthy cinematic endeavor. Damien Power’s “Killing Ground” is not quite such a film, but it does manage to craft a pair of truly complex relationships and offer up some disturbingly heinous violence.
