This generically-titled shocker claims to be 'Based on a true story'. But while one of the bonus features makes it clear that the pre-credit sequence has its basis in a supposedly real event, the rest of The Possession is so blatantly derivative of William Friedkin's 1973 horror classic that it might as well come with a label that reads 'Based on The Exorcist'. On a more positive note, the sheer quality of The Possession's AVC 2.40:1 1080p encode and DTS-HD MA 5.1 mix ensure that it won't disgrace your home cinema should you choose to give this Blu-ray a spin.
