I pretty much agree with TOML. Ozzy has done some great things in the past, both with Sabbath, and "solo" (Not really solo, he still had good bands, and great guitarists in particular). The Osbournes is funny (in small doses, not every other hour, in between Jackass and Dirty Sanchez repeats). And I can fully understand them using the Ozzy heritage to get Kelly noticed. But now she's been noticed, she doesn't have the goods to back up the attention. And it's only a matter of time that her music career disappears, and she probably ends up as a TV presenter (for example).
Ozzy is near the end of his career. Let's face it, he's a talented guy, funny, but he's pretty much shagged out now. He doesn't need the money, why not leave his fans respecting him, rather than milking the Ozzy brand dry?
