Wolfgang Van Halen is the son of Eddie Van Halen and Valerie Bertinelli.
His father died of cancer in October 2020.
He was not a fan of a show about his father's death, and he blasted them.
Wolfgang said the company was disgusting and pathetic.
He noted that they were trying to glamorize his father's demise.
The production company Reelz has not responded to his remarks.
The rock star bagged his first Grammy nomination but did not win the award.
His mother finally decided to divorce her partner of ten years, Tom Vitale.
Her latest lawsuit showed that the marriage was totally dissolved.
