An entertaining if not very original demonic possession slash zombie gorefest that, at the very least, showcases energy and zest.
As the epitome of seventies B-movie charm, it boasts the strong elements of enjoyable kitsch that one would hope for.
The exorcism makes a refreshing change in not being Bible-based, but this is strictly Hollywood horror by numbers.
Has its moments and there are a couple of good scares, but the direction is flat and static camerawork wastes opportunity.
Any suspense is dispersed in favour of splatter and nudity, the film throwing out the script and making it up as it goes along.
