i went to see this movie without thinking i was going to be completely engrossed in the film and its complex characters. The story starts with a young woman that is currently in divorce proceedings from her estranged husband, moving into a new apartment. Everything starts off OK except that during her settling in to her new apartment she answers the phone where a older woman on the other line asks for a man that doesn't live there. from there on a phone relationship builds with this seemingly unstable elderly woman and a lonely young woman going through a difficult divorce. in time, strange things begin to happen and the movie takes a scary turn, it becomes extremely suspenseful and scary even though there is a lack of blood and graphic violence. i found the movie very entertaining and with its numerous twists, a movie that made you have discussions afterward in the theater with your friends about who was who, what does it really mean and what was real or a dream. a must see movie!
