“Metal Lords” (*** out of four) was an affecting coming-of-age drama about two friends (Jaeden Mitchell and Adrian Greensmith) who see heavy-metal as their salvation in life in their deadend town but this all leads to complications with a group of girls (Analesa Fisher and Isis Hainswort) who they meet. Not much plot per se as it wanders a little in its second half but agreeably performed and directed by Peter Sollett and script (from “Game Of Thrones” writer D.B. Weiss) has some scattered effective moments. Metal gods Scott Ian, Tom Morello, Kirk Hammett, and Rob Halford all show up in minor cameos and Morello was one of film’s executive producers.
