It's not the best poliziotteschi for anyone involved but I will always have a soft spot for it, and it's never less than entertaining
Imaginative, confrontational horror filtered through Hammer, Bava, AIP and more.
Thematically dense, exploring objectification of women, male sexual psychosis and poisonous patriarchal homogeneity. Also functions as a literate, beautifully made, kickass low budget horror in love with its genre.
I really enjoyed it.
Additional pretentious film writer comment: try developing beyond a shallow understanding and appreciation of the myriad of historical and cultural inspirations for this film, you'll enjoy it more. But if you genuinely think this is in any way misogynistic, anti-feminist or pro stepfather/stepdaughter sexual tensions propaganda (arf) I feel for you, really.
