Firstly iwant to talk about bad sides of the film. In my opinion the movie is boring because of actings. Actually the story of the film is uniqe and goergous, not like actings. But the ending of the movie was predictable. I was predicting what would happen from the beginning. Of course there is a schizophrenic man. Still, I have to admit that they handled the story of a schizophrenic man in a very different way. It' s a good thing. Ok then let's talk about good sides of the film. First of all phone call scenes are amazing. It was super spooky. Also, the way the character dealt with this situation was very clever. I think people have such phone conversations in themselves. sometimes i think you encourage and humiliate yourself. So guys i think you should watch and interpret the movie.
