This mystery starts off rather compelling; and follows as intriguing. However, its continuously convulsing nature loses strenght as it culminates in a not so surprising conclusion (if I may even, predictable), which seems to not justify the illusion of a more complex premise.
SPASMO is an anti-giallo, more a mystery thriller than anything else. No murder scenes here but a lot of dolls lost in the forest. No sex but many close shots of guns and scissors. Robert Hoffmann looks a lot like Alain Delon and Suzy Kendall doesn't look anything like Romy Schneider. Already forgotten.
Highly preposterous but also highly entertaining giallo thriller directed with great style and energy by Umberto Lenzi, helped along by another effective score from Ennio Morricone. The plot bends credibility and logic at every twist and turn, but in a genre that prides visual flair and psycho-energy over logic, it's a great deal of fun for fans of Italian exploitation.
