Seriously, I can easily stomach a lot of on screen blood, gore and repulsiveness, but what really makes this film disturbing & uncomfortable to watch is how the doctor character keeps on rambling about the physical damage done to raped women. He, John Cassavetes of "Rosemary's Baby", talks about ruptured uterus, dry intercourse and massive loads of reddish (?) sperm like they are the most common little ailments in the world of medicine. That being said, "Incubus" is an ultimately STRANGE horror effort. It isn't necessarily awful  although it isn't very good, neither  but just plain weird. The muddled & incoherent script initially revolves on the hunt for a rapist-killer of flesh and blood (even though the title clearly suggests the involvement of a supernatural creature) and it never seems to stop introducing new characters. None of these characters, especially not the main ones, come across as sympathetic and for some never-explained reason they all seem to keep dark secrets. The aforementioned doctor has an odd interpretation of daughter-love and continuously behaves like he's a suspect himself, the town's sheriff (John Ireland) appears to be in a constant state of drunkenness and doesn't even seem to care about who keeps raping & killing the women in his district, the female reporter is even too weird for words and the Galens (an old witch and her grandson) are just plain spooky. All together they desperately try to solve the mystery of whom or what exactly is destroying the towns' women reproducing organs. The sequences building up towards the rapes & murders are admirably atmospheric and the vile acts themselves are bloody and unsettling. Basically these are very positive factors in a horror film, but the narrative structure is too incoherent and the characters are too unsympathetic for "Incubus" to be a really good film. Also, there are quite a few tedious parts to struggle yourself through (like footage of a Bruce Dickinson concert!) and the usually very reliable John Hough's direction is nearly unnoticeable. The final shot is effectively nightmarish, though. For me personally, "Incubus" was a bit of a disappointment, but there are still several enough reasons to recommend this odd piece of early 80's horror to open-minded genre fanatics.
