Sette orchidee macchiate di rosso/Seven Blood-Stained Orchids (Umberto Lenzi, 1972)
Elusive criminal kills one after another women, unified only with the fact that all of them stayed in the same resort hotel several years ago. The film doesn't contain garish formalistic crotchets, its cinematography isn't very bright, but the narrative energy of the movie keeps viewer's attention (unprecedented thing for a giallo film). You can guess the murder earlier than it's necessary, his logic is really silly, but director's competence is undoubtful. Besides, Riz Ortolani's music is very good. 6/10
