Hey 1960's thriller fans, don't get yourself all wound up over the fact that this is not a high budget Hammer film and you'll do fine and enjoy the flick. Bava has a style all his own, and folks it's here in spades. Haunting music, erie lighting, minimalistic effects, all used to his advantage to deliver a very moody, atmospheric chiller that will set you on the edge of your seat. Make some popcorn on a Friday night and break out some ice cold bottles of soda and have good ol time watching this flick in a dark living room right around midnight.
This is a typical horror movie of the era... which means that it's well shot, has rich atmospherics, and carries a creepy vibe throughout. However... it never delivers on the horror. For the times that it was shot in, it was probably groundbreaking, and the title is provocative. I "liked it" for the sets, old Italian ruins, and character creations.
What I expected from Mario Bava .the sets, the lighting. check out the color of the grass and of the stone walls in several shots for instance, my complaint is with the disc having no chapter selections ! Fall asleep 1/2 way through this one, and you will not be able to take up where you left off.
