A Lizard in a Woman's Skin (1971)

Paper dolls of murder victims > chalk outlines.  End of story.

Lucio Fulci does not get the respect that he deserves.  Sure, he's drubbed by critics, but those of us who follow Euro-cult and b-movies are used to that.  So-called "serious" critics routinely deride the work of a host of directors, from Jean Rollin to Norifumi Suzuki, as "just" exploitation filmmakers, as though the fact that these artists took advantage of new freedoms from censorship meant that their work was bereft of artistic contribution.
