What Happened to My Sister?

Please, do not waste even a second of your life to watch this movie! Terrible actors, easy predictable scenes and no any suspense at all ! I was so suprised to see how highly rated it is, not deserve even 1 as a rate. Actors overacting so obviously, and I even getting angry at some scenes why I am still watching it. Screenplay and camera movement looks like was doing from a useless teenager. I don't know, if couldn't trust IMDB rates , how could I find any nice movie in the future. Should be another type of voting maybe or any different source. Usually I have never watched trailers, because this killing the pleasure of the moves!
