Like many other reviews said before me. The movie was ok until the third act. But then it goes haywire and ruins the whole movie.
During the second act he gets haunted several times by ghosts and after watching the whole movie I can't see why. You can argue that they were there to help him escape, but he also needed to prove to his devilfriend on the outside that he was better than the others so that argument doesn't hold up....
After all just another Netflix horror/thriller movie.
