I don't know much about ghost stories, but I have been gravitating to them of late. This one is the most realistic one I have run into so far. A woman's twin-brother has passed away and she is preoccupied with an oath they had made, whoever dies first will try to pierce the divide and leave a sign for the other. There is a rather sadistic soundtrack consisting of a free-floating sonar-like program but instead of underwater, we get a generalized array of ambient tracks from whatever locale our POV character happens to be at the time and at an extremely high decibel level. If the idea is to keep the viewer a little on edge, it succeeds. There is an extraordinarily realistic visitation scene which frightens. There is a sequence where an unknown texter is harassing the survivor, which under the circumstances, is more than a little eerie.
The denouement is predictably unclear except perhaps for especially perceptive viewers of which I do not belong. But an explanation is there that seems quite convincing (I had to read it from a review) which I give the movie credit for. It's not just a scary story that leads nowhere.
