Lamberto Bava's cult horror film DEMONS truly rocks. Claudio Simonetti's (Goblin) driving score is augmented with hard driving tracks from Motley Crue, Saxon, Accept and more mainstream figures like Billy Idol and Rick Springfield (!).
The script (by four writers - I guess they each contributed an idea for a kill or two!) is absurdly simple: A mysterious new movie theater gives out comp tickets to an untitled film. The movie within a movie is about a group of young people who stumble upon a book of predictions by Nostradamus calling for Demons to rove the earth. Before you can say Lucio Fulci, audience members begin to turn into Zombie like ghouls.
Give Bava credit, he knows what his viewers came to see - Demons killing people. And, the first half hour is pretty intense. After the ten minute mark or so of introduction, it's shock after shock -- all with that driving rock & roll beat. In a way, Bava kind of shoots his shoots his load early on, as the last hour of the movie follows the basic horror flick plot of: Stalk. Kill. Escape. Stalk... etc.. It's well done and there are a surprise or two in the final few minutes.
The Makeup is generally good, even if the quality is variable. The acting is par for the course, but, Bobby Rhodes as Tony, a pimp taking two of his 'employees' out for a free flick, is boisterous fun. One of the lessons here is that there truly is nothing 'free' in this world - or, the next!
P.S. The ending is interesting as it seems to exist in the same 'Universe' as Romero's Living Dead series and the Zombi films of Lucio Fulci.
