Keep the lights on tonight, since Paranormal Activity 4 will certainly keep you awake! In the previous Paranormal Activity films, Katie (Katie Featherston) is possessed by a demon and kills her boyfriend, her sister and husband; 5 years later, a new family moves into a suburban neighbourhood in Nevada and strange things begin to happen once again. When Alex (Kathryn Newton) is left to care for her new neighbour’s son Robbie (Brady Allen), a mysterious presence appears on her webcam. Alex tries to uncover their new neighbours’ darkest secrets, but nobody will believe her – until it’s too late. With production of Paranormal Activity 5 already underway, this supernatural horror Blu-rayis a must-have.
