"The crew for a fake TV ghost-hunting show has an unfortunate brush with genuine supernatural phenomena in "Grave Encounters." Debut feature for duo Colin Minihan and Stuart Ortiz, who've dubbed themselves the Vicious Brothers (not to be confused with fellow horror helmers the Butcher Brothers), treads by-now-familiar scary-mockumentary terrain... Still, pacing is taut, the setting eerie, and eventual scares are fairly effective if never particularly original. If a somewhat formulaic air hangs over whole enterprise, it's nonetheless creepier and less cookie-cutter than your average mainstream slasher. Tech/design factors are polished within the faux-verite concept." - Dennis Harvey, Variety
