The premise of this movie held promise, though the way it was brought to life fell short. Jessica Chastain portrays "Sylvia," who navigates a career in social care while raising her daughter, "Anna" (Brooke Taylor). Her daily routine, clearly shown by her habit of locking her door and setting her alarm, is rigidly organized and predictable. She maintains a close bond with her sister but has no contact with her mother. The two women go to a school reunion one evening, and after leaving early, Sylvia finds herself being followed home. It was an unpleasant night, and the next morning she discovers a man asleep outside her front door. Looking through his wallet, she identifies him and contacts his brother, "Isaac" (Josh Charles), who explains that "Saul" (Peter Sarsgaard) suffers from memory problems. The question arises: was he stalking her, or is there something else behind this rather drawn-out situation? Chastain's performance is decent, but I felt the narrative introduced a number of incidents that seemed arbitrarily inserted to propel the plot forward. A lot of them appeared overly contrived and were used simply for dramatic effect. The final scenes didn’t ring true, and at times the movie resembled an over-the-top television drama. Too much of the story relies on chance occurrences, and important details about the characters are revealed in a disjointed manner. I felt empathy for nearly everyone involved, but I wasn't really drawn into what was happening.
