The only reason all the metal documentary shows cover New Wave of British Heavy Metal is so the can talk about Iron Maiden. There is no other reason. You never see them spend more then a few seconds talking about Saxon or Tygers of Pan Tang. If it wasn't for Maiden, NWOBHM would never be touched on, since no bands really went anywhere.
