Parents need to know that this sci-fi miniseries focuses on characters' desperate -- and sometimes deadly -- attempts to collect a host of objects with paranormal powers. Their allegiances to various cult-like groups often change throughout the series, making it difficult to discern whether individuals have good or bad intentions. The main character is a single father searching for his young daughter, who has fallen through a portal to an alternate universe. Violence is prevalent and can be graphic; in one scene, burn victims are shown hanging from the ceiling and a wall, and in another, two people are shot and killed. There's a lot of suspense and spookiness throughout the show (some scenes include the ghost of a woman who's screaming and reaching out for help), and a few surprises that will make your heart pound. Teens and adults who can handle the eerie subject matter will enjoy the well-played suspense and intriguing storyline.
