A gothic, romantic/horror film-- and the first Italian horror in color-- Mill of the Stone Woman falls into the same trap that the lesser of gothic films do: it does well in character relationships and in romance, but isn't as strong with the gothic and horror elements, lacking urgency and sustained tension and threat. These pacing problems make it dull and stagnant, instead of suspenseful and emotional. Ungripping.
Eerie, stylish gothic romance. Not essential, with many flaws but a nice discovery if you are in love with classic euro-horror cinema (from the Hammer, Amicus company...). for the mood and topic this is somewhere between House of wax an blood of the vampire.
