Jack Osbourne wants to set the record straight about his famous father. And that means taking a few swipes at the MTV reality show that put his family back on the map.

"I think The Osbournes, to a degree, tarnished the public's perception of my dad as a bit of a senile, funny, bumbling guy," Jack tells Rolling Stone magazine. "Yeah, my dad can be that guy, but it's not [all of] him. "

Now Jack is trying to rejuvenate his dad's rocker legacy. He has recruited his own pals and his dad's former bandmates to contribute to a documentary he began shooting in January.

The result, he told the music mag, will be a kind of filmic memoir. The Black Sabbath frontman is dyslexic and "refused to do a book," Jack adds. "So this is more like a talking book, a really thorough autobiography."

And despite their close family bonds, Jack insists the film won't be a puff piece.

"My dad's not an idiot – he's nothing short of a genius, in my opinion," he explains. "He does have huge flaws, and we're trying to really paint an honest picture of that."

The production schedule for the film – tentatively titled John (Ozzy's given name) – is open-ended.
