First, there's nothing especially new here. The film has several of the hackneyed horror elements: a group of young people, an isolated setting, a killer from the past, and an evil from the past recurring in the present. In this sense, it is rather like a combination of I Know What You Did Last Summer and Ghost Story. Oh yeah, and there's a fair amount of the characters having sex before the killing begins. So the movie's not all that original.
Then again, there isn't much that is original in American horror these days. So, taking the derivativeness as a given, I find this movie fairly good. Allie (Kailin See, Snowglobe) goes in search of her father, who has disappeared, perhaps in connection with an old series of crimes. As it happens, an innocent person was tortured by a mob for those crimes, and her ghost is out for revenge. That's pretty much the plot. The rest is more or less by the numbers, albeit with a fairly good cast, nice effects, and a small twist at the end to keep the film from being a one-dimensional cliché. There are certainly better films out there, but there are also worse films.
