Every documentary on heavy metal sucks
Above is a two-and-a-half hour documentary called Heavy: The Story of Metal, which originally aired in 2006 on a cable channel here in America called VH-1. I don't know how long it's going to stay online, so watch it while you can before it gets pulled. (ETA: Yep, it got pulled, sorry, but I still got stuff to say about this.)
Is it any good?
No, it sucks.
Note up front: Yes, I made the above image. It's the "I'm as mad as hell" scene from Network.
If you ever wanted to know what kind of musician puts forth the most effort and gets the least results, the chiptune musician is it.
