Global metal is the second Sam Dunn Heavy Metal documentary. The first, 'Heavy Metal: A Headbanger's Journey' is, so far as I know, the standard documentary covering the Heavy Metal scene. It does an excellent job of both detailing the history of Heavy Metal, and explaining its appeal, but it is focused on explaining Heavy Metal to those who do not know much about it, and because of this, might conceivably have less appeal to hardcore metalheads.
'Global Metal" by contrast, is probably better calculated to bring new information to the attention of experienced Metal fans, but is not a condensation of extensive knowledge about the global metal scene, and it shows. This is not a bad documentary, but as exploration on Dunn's part, and constituting a light survey, it is not quite so informative as the first.
I would further note that this is not a comprehensive documentary on metal throughout the world, but is more a "metal is spreading to exotic places" sort of documentary. This fact is not a criticism, but knowing this is likely to be important to at least some of the people looking up the film on IMDb.
A truly comprehensive film covering the history of metal would necessarily be of epic length, considering that this documentary does not cover the US or European Metal scenes in any significant fashion and yet at 93 minutes, the film does not seem to be especially dilute.
