If you're going to watch an 80's film you'll expect to see mullet hairdos. It made me laugh when one of the students said to the protagonist (heavy metal fan Eddie) "You should be normal" because they ALL look the same to me! There were cameos from big stars, although Ozzy Osbourne was playing a vicar so it was a tongue in cheek/weirdness. The music in this isn't "death metal" at all but those saying it is, know zero about metal! And Sam the evil entity who was a dead rock star looked like he was out from the 70's glam rock era, as it looked as though he was in platforms. 80's horror is good but this one turned out messy.
