Suspenseful and intense!  This film by director Sergio Martino effectively brings the suspense factor to the hilt with slasher scenes and bloody shots of persons being killed and sawed to a bloody pulp.  There was also a scene where a man was pinned to a wall and almost crushed, that was scary.  But while this giallo film satisfies horror fans with the suspenseful scenes I also find it reminiscent of the fashion statement of the '70s, it brings one down memory lane to that part of history where clothes are fashionably hip and the locations are breathtaking. Worth checking out not only for the screams but also for the truly authentic retro vibe of the movie.
