Bill Zebub is the bastard cousin of John Waters and Rob Zombie. If you can grab his style, it's his best work yet. I am a fan of some of his work, and hate most of it. "Dirtbags" is easy to laugh at because he knows how to make himself laugh. Fat Slob Druggy moron on a couch masturbates and takes drugs. A minstrel show black-face drug dealer and numb-skull Christian daddy interact as the script becomes didactic with a statement on human behavior. All an excuse to offend those who don't get Bill Z. Like watching a stand-up comic wizz on the guy in the front row who won't crack a smile. Thats the Joke! Go with it, and watch this movie from the back row.
