It's the second time I read this page and I can't understand why Contronatura (aka Schreie in der Nacht aka The Unnaturals)is still waiting for 5 votes! In fact, I think, it's a really good italian horror, a kind of "summa" of all themes of this particular genre. The director, Antonio Margheriti (also writer, in this case) is very skillful and builds his movie around a number of impossible flash-back, that articulate a disquieting narrative of murders, guilty men, strange women...I can't speak english very well, so I can't describe in the right way this movie, but if you like italian horror, you have to see Contronatura!
