The first hour or so of this film is very slow moving and tedious, in fact I came very close to giving up on it, but I did persist and the pace and interest levels improve after the first hour. Like the director's better known Blair Witch, this film involves a creepy forest setting. It is another one of those stories where a group of American teenagers go off to spend some holiday time together in the middle of nowhere, and then spooky things happen (you would think the youth of America would have learned it's lesson by now)! The difference here is that one of the teens lost her twin sister the year before and is returning to the house where she spent summers with her. Her dead sister is very much on her mind, even before she suspects that her twin might be trying to tell her something from beyond the grave.
One original feature is that this film does not turn into a bloodbath. All too often the formula is that kids go into the woods for a holiday, meet some weird locals or a something supernatural, and get picked off one-by-one, with the only difference between films being the manner of the gory death. With this film there are some moments to make you jump but everyone survives.
