Watching low budget horrors from this period is usually a completely awful experience. The first 20 minutes were above average for what is was. Lots of quick paced fun scenes with disgusting people being trashy and evil. A few funny lines. Exactly what I like. I thought it would be a classic.
The fun of the movie fades when the story revolves more around the drug, music and other teen stuff. It missed the mother and brother being around to create the bizarre entertainment. So with little interesting characters left or interesting plots and scenes in the second half it kind of died a premature death. Shame.
If you're into cult horror or just 80's comedy horror I'd definetly check it out. 5.5/10
