With a title like 'Excorcist 3', one doesn't hope for much. But in fact, this film is really only so titled to exploit the value attached with the name, and although it was written (and also directed) by the writer of the original film, it's actually a stand-alone movie in it's own right. And while William Blatty may be hard pushed to rival the efforts of the original's director, William Friedkin, he doesn't do too bad a job: he's a little over-reliant on abrupt cutting to achieve his shocks, and the budget for the special effects was obviously inadequate, but this is a suspenseful and chilling thriller. All supernatural movies suffer from a degree of innate silliness, and satanic movies perhaps especially so, but this film is constructed as if it was a conventional serial killer thriller, albeit an exceptionally dark and creepy one. As the signs of actual devilry begin to increase, the detective leading the case (played brilliantly by George Scott) starts to wonder if he's going mad. Only when the film is forced, near its conclusion, to represent the nightmare literally, does it inevitably become a little daft (but that charge could even be levied at 'The Excorcist' itself). I'm not generally a huge fan of horror movies, but this one is definitely above average, for its skill in modulating the tension and in restraining from excess until its final scenes. In conclusion, ignore the title, and watch.
