Oh dear. It's the usual tragedy: a flicker of an interesting premise wasted by a singularly derivative script wholly dependent on cheap, predictable jump scares, undercooked plot elements and a hard-headed anti-Science bias. Should 'Pet Sematary''s Stephen King have sued for plagiarism?
Un update to the "Pet Sematary" story in a weird science "Flatliners" scenario. This reabilitation of an old narrative gives it a modern frankenstein feel and, sadly, a underachieved paranormal ringu-like aesthetics. The most predictable and anoying aspects, though, I found, were the thriller constructed narrative and the female trauma turned to histeric rage background theme. Oh, and not that scary, too.
