Though I'm not quite as enamored with the film as others here, there is still much to enjoy in this sorely neglected tale of a young man researching a creepy old windmill's lurid "carousel" and his love for the owner's mysterious daughter.
Made at the same time as Bava's "Black Sunday", Ferroni's "Mill" relies on and succeeds at it's goal for the same reasons- Atmosphere in abundance and true artistic flair. Every inch of the windmill is ominous and each room (and there are many) has its own distinct feel, lighting, and color palette. With this strong foundation in place, the movie builds in the details, including a wild hallucination scene, the actual workings of the carousel, a daughter who appeared very dead but is soon quite fine, and many others.
Despite being a visual feast, well acted, and having a solid (if not overly original) plot line, the movie still suffers from a sizable problem- Pacing. As a die-hard fan of '60's horror, I have no beef with a deliberate build-up, but in this case it goes a bit overboard. There are a fair share of scenes that are filled with stretches of unnecessary dialog and lots of wandering around the mill with no real reason to be found at the end. Tighter editing would have helped immensely.
Flaws and all, "Mill Of The Stone Women" is a classy film that needs to be seen. Had I watched it just once, I have little doubt my rating would have been higher. Give it a one-time viewing and absorb it for maximum effect.
