This movie is actually kind of decent. It's not the typical horror movie, it's more in the lines of a thriller where it keeps you guessing what's going on.
I know there might be a few plot holes in the movie, but if this storyline had a Hollywood production, better makeup and a recognizable face as the leading actress, this movie would actually be considered a very good thriller.
The first 40 min. of the movie are kind of slow, but it gets better.
