I had some pretty strong issues with this one. First, David Hemmings is fine, but the movie becomes far more interesting when he's sparring with Daria Nicolodi, and the film seems to forget about her for so long, I assumed it was done with her, and the suddenly she just re-appears. I guess people love the Goblin score, and as music it is perfectly fine, but I found it continually jarring and distracting, almost like the film was playing Yakkity…
Watching this you can see how it was written off at first, given the misogyny underlying so much horror, and why it has subsequently grown in reputation. I was expecting more of a body horror theme, and it is not that, but it is a fun movie that takes the theme of female friendship very seriously. It also displays a sophisticated understanding of power and limits of female sexuality, which is a subject dealt with poorly just about everywhere. And, a bunch of teen boys get killed, so that's fun.
