Upon first viewing, I did not know what to make of this movie. It is certainly interesting, but non-linear and difficult to understand. "What is going on?" I thought. A second viewing made it clear to me: this really is a near-masterpiece of giallo/thriller-cinema! From the haunting melody during the titles until the totally surprising and shocking ending, you will be mesmerized, confounded and thrilled. Mimsy Farmer walks around in semi-interested fashion for most of the time, but that is very much in tune with the whole story. A highly effective performance. The other castmembers are adequate, nothing more. Beautifully and imaginatively directed by Barilli who holds you attention even during scenes that could easily have been boring in their complete uneventfulness. And most scenes are accompanied by one of the most effective scores in a giallo ever heard. Properly marketed and aimed at the right audience, this film could be a future cultfavorite. A must-see for the adventurous moviegoer!
