This show is absolutely ludicrous and is trying to rewrite history. Dee Snider is the closest thing to an actual metal artist, but he hasn't done anything notable since "Stay Hungry." He reminds me of a high school football player who spends decades reliving their glory days.
Most of the true metal fans laughed at Kip Winger long before Beevis and Butthead. He was a joke, and now he's a crybaby. His "music" didn't have any substance and it was hard to tell the difference between him and the women he was objectifying.
It's no surprise that an industry that was all about the looks and clearly not about the music crashed and burned. They didn't need Grunge to do it. They were devoid of any real substance and so most people had no problem forgetting them. Note that during the same time Pantera, Megadeth, and Metallica had some of their best years. I laugh at all the hairbands and their fans crying about grunge instead of going out there and making good music to stay relevant.
This show largely perpetuates the same mindset while ignoring the real metal bands who kept putting out quality music. I say good riddance.
