This Spanish made horror about the demonic possession of a 15 year old girl, is set in England and stars English actors. Despite being derivative and cliched at times, there are enough twists and ideas here to ensure it succeeds in its own right. There are interesting studies into the motivations of the characters in the film, especially the brother of Emily's mother, a disgraced priest who the parents turn to in desperation to perform the exorcism. Revalations regarding his true calling provide the most enjoyable plot twist in the film.
The portrayal of Emily Evans is also interesting, Emily being a typical troubled teenager, whose turbulent emotions allow the forces of evil to take hold of her. Less successful are the portrayal of the parents, both coming across as rather one dimensional.
Somewhat lost in all the hype regarding 'The Last Exorcism', this subtle little study into the nature of evil and the existance of the Devil is well worth a visit. This dvd release is a bare bones affair, with no extras to speak of. 4 out of 5 for the film.
