There may not be a better commentary on the vapidity and pointlessness of our culture, where everyone has too much education, too much time on their hands, and not nearly enough purpose to their life. The TV fetishist, the senior citizen raging against the machine (seriously, is their anything more pathetic than an elderly anarchist? An middle aged gangbanger, I guess), the stoners, the conspiracy theorist: this is who we are. This is what we've become.
If you've ever been to Austin, you've overheard the conversation where the guy argues that Scooby-Doo is a corporate effort to impose groupthink on America's Unsuspecting Youth.
These are disconnected, unhappy people, so obsessed with navel-gazing, endlessly pacing the floors of their own circumstances. As social commentary, it's brilliant.
