It was a bit slow in the beginning and middle of the movie. A woman working as a customer service call center from an isolated area. It shows the use of social media, selfies can lead people into your life that you don't know. The terrorizing guy does his thing by seriously threatening her over the phone and then tracking her down through her social media accounts. After some cat and mouse chasing in the house and he beat her down She then gets the best of him but the ending was STUPID and ruined the film, after that ordeal your not just going to go back to work. Films now days don't know how to deal with the ending.
