If I told you it was a movie, written by D. B. Weiss (of ‘Game of Thrones’ fame), about two lowly high school outcasts who form a heavy metal band and then recruit a loner cellist to join in the fray, would that sound interesting at all? Turns out, yes. This out-of-nowhere Netflix comedy hits all the proverbial right notes and avoids winding up as yet another coming-of-age teen flick. It’s fun and irreverent and crazy and even a little bit sweet. Plus—killer soundtrack and some nifty metal-god cameos.
