Brian Formo’s review published on Letterboxd:
Hair Metal is such a joke that Penelope Spheeris' follow-up to her punk doc feels like a Christopher Guest mockumentary when it's ridiculously real. For all the lounging in bed posturing of Paul Stanley—with women at every limb—saying that he can't fall in love with them, it's obvious that Spheeris' interest is mostly in the underdog and the ill as she let's Stanley and all the successful rockers look as ridiculous as possible but is more at home in the hot tub of a suicidal metalhead who's still trying to make it or an alcoholic rocker who's drowning himself in alcohol while his mother sits poolside. If the first Decline was about young anger and fringe society, the second is the ridiculousness of hyper capitalism, and the decline of ideas and intelligence that comes with it. It's crazy how all these people think every crowd is a million people lol.
