It's a question broached by writer Douglas Kern for TCS Daily, and what its impact on popular culture says about the human condition:
I met dozens of Anna Nicole Smiths back in my state prosecutor days: women whose looks and shamelessness far exceeded their self-control and intelligence... Right now, in family courts all over the United States, the Anna Nicole Smith saga is being replicated a few hundred times every hour... [W]hen you strip away the money and the impossible good looks from this sorry tale, you're left with a simple story: "irresponsible but sexy person screws up lives of family and friends." And that's a story to which nearly everyone can relate.
I can't say anything like this has happened in my family. If we didn't know how to behave, we didn't get away with it for long, and if we did, we had the good sense not to brag about it. At least not at reunions.
In any case, it may be one of the few items on the entire Anna Nicole Smith saga that is actually worth reading.
And so it goes.
