Query: A huge downer

I almost gave this movie two stars for its professional acting and cinematography, however, the subject matter is so depressing and is too similar to other creepy thrillers, it also has the same "surprise" ending as High Tension, which was a much superior horror movie.I didn't feel entertained nor did I like the selfish characters. The subject matter was a major downer and the ending was just lame.
