Much better than it's reputation, far from being 'one of the worst movies ever made', I actually found this an entertaining watch. It's well-shot and directed, It has plenty of goofy moments, occasionally veering into outright bonkers (the climax in particular feels like a fever dream), but it's never dull, and feels almost charmingly bold in its lunacy. By no means a great film, I'd still rather have this entertaining nonsense than a 'play it safe' retread sequel. If you can roll with the madness, there's plenty to enjoy here.
Not as horrible as I was expecting it to be considering the reputation the film has garnered over the course of four decades but it is evidently a big step down over the first film. The first of many problems with this film however involve the lack of an exorcism that has any real impact on the plot (there is one in the first scene which is effective but doesn't compare to the exorcism scenes in the first film), there is the lingering question of why the death of Father Lankester Merrin that occurred in the first film is being investigated after four years, then the pacing is all over the place with long stretches being boring, I don't believe for one moment in the techniques used at the psychiatric institute that move the plot along, the score doesn't come close to being as good as before and it suffers from the same issues that the first film had (notably lacking any scares and I doubt I'm the only one on that front). It does have some positives however as the cast is good, there are some well done visuals, the final act has a couple of decent action scenes and it doesn't portray Africa in a stereotypical and negative light.
What a boring film no suspense at all and a very slow and boring story. No where near as good as the first film.
