It could have been a better movie. The ending was good, but I don't think it suits this movie. I was expecting something better. Selma Ergec gave a good performance. Mehmet Gunsur was always an "actor" I didn't like. He tried to give a good performance in this movie, but he didn't perform well here either. I expected the sound to be more terrifying. This movie didn't turn out as I expected, because I think an unknown voice is more frightening than an unknown image. Good idea, but it didn't happen.
