This is another case of a movie which seems to have been highly underestimate. This is not the crap the score rate seems to testify. When you approach such a product a minimum of historical perspective should be the norm... we cannot judge a movie filmed in 1971 with standards of today's taste. This is a thriller with a weird plot,a definite stress on turbid sexual themes, some gore scenes, some Gothic and fetish elements that can make the joy of the true Italian b-movie lover. In my opinion this movie has everything a movie should have to let you spend an hour and a half before the screen and even enjoying your time. We are a few and we're happy, please let us dream alone.
