I have only seen it once - I am 39 years old and played "original, non-death, overly self-indulgent, melodic heavy metal" in the days when Iron Maiden, Metallica and Megadeath were fairly new to most people.
The one episode I saw reminded me so much of everything that was going on with the "metal crowd" back then that, as much as I wish I was never a part of it, made me laugh and even get a little nostalgic.
I then proceeded to have a flash-back, downed an entire bottle of Purple Passion, put on spandex pants, a muscle shirt (which, on me should be called a "look, I have no muscles" shirt), proudly put on foot up on the arm of the couch and began air-bassing Steve Harris lines aiming my imaginary bass at an imaginary evil monster who was attacking my imaginary, head-banging mosh pit, and the rest is a blur...
But my friend told me I am not allowed at his house any more. He is still trying to convince his kids that "Eddy" is not going to get them...
