What sets Dario Argento apart from many of his contemporaries is his success with visual imagery. In a style where sudden visual shocks are used to thrill the audience, Argento creates elaborate deaths which cannot be quickly forgotten. The highly involved double-murder towards the beginning of the film still remains one of the most memorable scenes in horror history, standing next to the Psycho "shower scene" in pure sensory input. And in a technique so powefully employed here and here alone, Argento sets scene after scene aglow with color, using it to express the mood in ways only the subconscious can fully appreciate. All around, this is an excellent addition to the genre of horror cinema, one of the most expressive films to ever plunge a knife into the psyche of its viewers.
