Interesting, complex look at a man who must kill young brides in order to unlock the secret of who killed his own mother. With each hacked bride, the main character of Harrington sees more and more of his terrible childhood memory when he saw his own mother axed. The acting in this film is nothing terribly special, nor is the story, but Bava'a direction is a visual treasure to behold. As always, he makes the most he can with the camera lens. Some of the shots are inspiring as Bava directs our attention through small orifices sometimes like a small window. His use of a room with mannequins is very effective too. Bava even has fun with his little joke of having Harrington watching Bava's own Black Sabbath on television when having just killed his wife he is visited by the police. Style and visual artistry ripen all around only to be harvested by Bava's gluttonous camera lens. The plot, although missing huge pieces of coherence and logic, is fairly well-crafted. The acting is adequate. I particularly liked the actress that played Harrington's vitriolic wife and the character of the police inspector.The sense of the sixties and fanciful colours pervade almost every scene, and the soundtrack is very suitable to this material. For some horror fans, the film may seem somewhat slow, but it kept my interest throughout.
