Metalocalypse (2006)

Brendon Small and Tommy Blacha imagined a melodic death metal band, Dethklok, so famous that by the end of season two it ranks as the seventh-largest economy on Earth. The music is the real draw, and it escaped the show: The Dethalbum debuted at number 21 on the Billboard 200. It ran from 2006 to 2013 across four seasons; most episodes are 11 minutes, while season three's run 21. The 2023 film Army of the Doomstar picks up the story. Baffling level: low, unless you hate loud guitars.
