Ozzy doesn't beat his kids.
Ozzy tries to talk his kids out of drinking, partying, and drugs, et cetera, and freely uses himself as a negative example.
Ozzy has always taken his family with him on tours so they could actually grow up as a family.
Ozzy supports his kids in the things they try to do.
Who gives a damn whether they swear a lot? The show is funny, mainly because it's funny to see Ozzy Osbourne being a father and doing all the normal things that all of us peons do.
That being said, MTV may consider it somewhat tongue-in-cheek to call it a family values show, but it's not entirely untrue.
I'm certainly addicted to watching it, I wish it was on more often. And I hate that they're considering doing the same type of thing with certain other stars. No need to take a good idea and then cheapen it by running it into the group with crappy knock-offs.
