WHAT'S IT ABOUT? A metalhead films himself making a film about heavy metal, tackling everything from its origins through to Norweigian church-burning nutters.

ANY GOOD? Welcome to non-boring documentarysville! Essential viewing for anyone who's ever banged their bonce to an AC/DC powerchord.

GREAT BITS: The Twisted Sister courtcase, Slayer's big beards and the drunk Mayhem psycho calling upon the powers of Satan and telling everyone else to f**k off.
