Some of the actions of the metal/punk killers reminded me of the crimes of Jeffrey Dahmer, Richard Ramirez, Richard Chase, the Hillside Stranglers and even Ricky Kasso.
Not that I know anything about that stuff.
But what really surprised me was the esoteric knowledge the plot shows, like mentions of Saturn, Tarot cards, and blood rituals.
Some of the stand out scenes are a live metal show, a stray cat carcass being eaten from a pizza box, the great twist ending, and the main character brutally beating a woman, drinking her blood, then pulling out a guitar and starting to sing. That one it's such a randomly bizarre scene that it creeped the hell out of me.
The other scene that got to me was when a guy got shot in front of a poster of the classic John Waters's film Pecker. Now why would anyone ruin a perfectly good poster like that? Seeing blood dripping down Eddy's paper face reminded of some childhood nightmares where young John Conner would get killed at the end of T2.
The scenes of David the rock Nelson gives you a much needed break from the disturbing horror. Nelson is like a funny Uncle reassuring you that everything is alright, that it was all just a nightmare and that John Conner didn't really get his brains blown off in T2. This is another SOV gem from blood sick productions.
