Generic giallo junk, lightly enhanced by Argento's stylized approach to violence/action sequences. Dialogue scenes are shot and staged with the enthusiasm of a root canal. Plotting and characterization an afterthought.
A hollow shell of what he would become as a filmmaker.
Excellent. Well paced, no deceptions, but just enough slight of hand to make it all play.
Great movie. Great to see Tony in the movie. Keeps you glued to you seat. You need to see it right to the
"Bring in the Perverts! Look @ them carefully & see if you recognize anyone..." A friendly warning to all you gore-hounds; don't expect L'uccello Dalle Piume Di Cristallo to deliver much. His trademark stylized violence hasn't been fully formed here. Its more like a random-out-of-nowhere-scratch-from-your-pet-type violence. "Whats the matter? You don't like cat?"
Also Noteworthy: Morricone's "lalalalalalalalala" score.
No better than a bad made for tv movie.
Argento's first film, but not his best. still a classic nonetheless.
