Suspect Zero is a film that explores criminal and psychological themes. Among the most interesting and unsettling is the possibility that a serial killer exists who leaves behind no patterns or clues but simply missing persons and unsolved murders. The themes alone earn a caution to the film’s viewers, especially as characters discuss the traumatic experience of “getting inside” a murderer’s mind. But Suspect Zero also includes the use of special mental techniques to gain knowledge of geographically distant events and of the future. This would probably fall into the category of the occult, even though demonic powers are not directly mentioned or invoked. Finally, the film includes objectionable language, violence, sexuality and nudity.
