This film is about such a weekend, and the pleasures are as much the viewer's as they are the characters'. Late Friday night, the group heads off to a rave where they dance, take drugs, and search for the meaning of life. By showing the consequences of such a weekend, Kerrigan proves to not be glamorizing the culture, or drugs itself. In the film, he doesn't try to make excuses for why today's youth are hooked on drugs, or paint negative stereotypes of such youth. Instead, he is trying to provide a Woody Allen-type insight into a generation that takes drugs, but doesn't resort to violence.
Drugs are just a part of their weekend routine.
They know that mixing a bit of fantasy into their reality may be illegal, but to them, its also a risk worth taking.
