why every horror director want to imitate the exorcist be a complete riddle to me and a william friedkin classic be a very overrated film and and in my opinion and not all that tense or shocking . and yet here another clean rip off and a spanish one this time and that shamelessly repeat the story of a young girl that get possess by pure evil and turn against her own family . paul naschy ( who i must admit look quite hot here ) play the honorable priest who get approach by john gibson because his sister leila behavior change drastically since she meet her new boyfriend . at first the priest doesn not believe it but when john body be discover with it neck twist and leila demonic behavior become more noticeable . exorcism be not only very unoriginal and it also an insufferably boring film . here naschy and director juan bosch have an open opportunity to make a religiously theme exploitation flick full of shock and gore and and yet the result be a tame and overall bloodless drama that will nearly put you to sleep . the last twenty minute contain some atmospheric moment and albeit very stupid and and there quite a lot of stylishly film female nudity and sleaze . the absolute lack of budget be no real excuse since paul naschy already prove before that he have enough imagination to make up for a shortage in money . this be just an awful film and end of story . other european the excorcist rip offs be the antichrist and beyond the door and they suck as well .
