There are things to admire in this film. The cast does a great job. In fact the very fine casting work matches a slate of interesting, differentiated characters developed in the script. However, good horror/suspense films establish some ground that gives us a greater understanding of the source of terror. There's a point to the horror. Here, there's no effort to establish anything like this. At best we have a picture of unsettled spirits from beyond wanting to inflict maximum pain and suffering on living people. That's at best. Even this leaves much to be desired. Why are they unsettled? Why are they motivated to torment people? What is the nature of these spirits from beyond, and what do they really want? The filmmakers don't appear interested to offer any point behind their slick production of stomach-churning gruesomeness. That can work for some films, maybe, but other qualities - camp, humor, smart ironies, a sense of adventure and so forth - usually come into play for something elevating and positively entertaining to occur. This film, on the other hand, is half-baked in this respect. And with so much serious gruesomeness it leaves a bad taste in the mouth. But it's worse than that. It plays on themes of suicide, grief, and serious mental illness like schizophrenia. It does so without a sense of responsibility. In a world where terror happens for no reason, serious issues like these are left dangling. The result is like someone poking grotesquely at a wound because nothing else interests them. Unfortunately this film is more diminishing and gross than positively entertaining.
