For an old metalhead, this is an interesting show for people who liked the Headbangers Journey video. The disingenuousness shows up when you're reminded that Sam Dunn created his own "family tree" and is basically indulging himself with this show. He's practically begging the grunge bands to declare themselves "metal" and I'm sitting here going, who cares? LOL. I guess as an anthropologist Sam Dunn is naturally predisposed to dissect his obsessions like this, but he needs something else to do. A Rush-style biography of Scorpions or Sabbath would be good.
