Loved it. Great suspense, disturbing murder scenes. Not too gory, but the suspense makes up for it. Very tense, the closeups, the pre-murder lighting and screams, the sound of the heart stopping. The victims' desperation is well played. Music is great to set you in the era, but you'll find it cheesy if you don't like 80s stuff. Some of the nudity was perhaps unnecessary but still stylishly done. The movie is weird but well executed. It isn't as gruesome as a gore flick, but I think it was more disturbing as it provides greater immersion. The slow killings are a shocker as you can feel them as real. I found myself trembling several times watching this, both by the murder scenes themselves and the suspense going through all the movie. Great camera shots, great scene composition, awesome lighting. The plot is simple but it works. It's interesting to watch the students accusing each other of the murders. There's an unexpected plot twist that I found rather interesting. Don't watch it if '80s cheesiness puts you off. In my case it was a plus. My first venture into giallo cinema and it satisfied me beyond my expectations. If I can find similar movies will definitely watch them. Last recommendation: do yourselves a favor and don't watch it dubbed, watch it in Italian as it's intended to be watched. Dubs for low budget movies aren't precisely good and will make the movie look fake. Get Italian audio with captions for maximum enjoyment.
