I recently saw Satan's Slave as well but Satan's Blood is far superior in my opinion. I really love this film. The atmosphere is amazing and truly foreboding with very exquisite cinematography plus the main girl Sandra Alberti is breathtaking. I got pulled in right away despite the tacked-on intro, which I still think is interesting, but you can tell immediately something isn't quite right as our innocent couple suspects when they're invited to a home far off the beaten path. I also really like Nude for Satan but Satan's Blood is far more respectable and fascinating. Sure, it's sleazy but I think that's a huge part of the appeal.
