Letizia moves to her aunt and uncle after having lived at school. They are unable to have kids themselves and are hoping for her to be able to help them get through some of the grief they have been feeling. But that's before she starts controlling the family into destructive behavior through the use of her mind.
"Diabolicamente... Letizia" is a much more appropriate title than "Sex, Demons and Death". If anything, I'd call it just "Sex" - that's the only truth there is to that title. People do eventually die, but they're really tame death scenes and it's such a small part of the movie. As for demons - none. At all. It does dwell into the occult and voodoo but it's never more than just an erotic drama with occult elements. It's a shame really, since I had been missing a really good occult film for a while now.
Letizia is a girl with some pretty pointless mind powers (moving cushions, giving her aunt hallucinations, and getting people to have sex with her or each other) who ends up using them on her aunt and uncle after they let her live with them after school. It's not a bad set up to have her manipulating them the way she does, and at times it's done very well, but there's sadly a lack of suspense in the story. The closest we get to suspense is when we in a brief sequence see Letizia as a bearded lady (?). Other than that it's sex and brief encounters with a weird mustached man (who occasionally wears a poor Halloween mask of a skeleton) who later turns out to be the mastermind behind Letizia's powers. Sounds intense, doesn't it?
But it's fine. We saw it coming when the distributor (or whoever decided on the title) chose to call it "Sex, Demons and Death". It was obviously an attempt to garner interest in it, and we've seen it done before. Therefor I wasn't sitting there expecting either of it to show up within the film. "Sex, Demons and Death" isn't all shitty - the story itself might not be well-executed, but it's entertaining at times, and Franca Gonella who plays Letizia isn't too bad in her role. I guess sometimes you need to let your guard down and let a movie be whatever it wants to be.
Fact remains though.. the entire movie believes that it's a lot more suspenseful than it really is. Truth is, there's not a single scene in the movie that is either thrilling, frightening, intense, atmospheric or even surprising. That's not to say it's a complete waste - if you want a very innocent Italian horror movie whose plot mostly consists of people randomly having sex with relatives or people who work for them, this is a good movie to go for. I'm gonna forget about this movie as soon as this review is uploaded, but some people will enjoy this a whole lot and that's a fact. The why's are beyond me.
