3/10
Calling this film stupid is like saying David Cameron's a public schoolboy. That's the name of the beast. Whether you like it or not, depends on your tolerance for an adolescent fixation with heavy metal, along with an obsession with bodily functions and a fear of sex with men.
Jack Black and Kyle Gass are Tenacious D; you know Black from School of Rock and High Fidelity, but Gass is his partner in their mock-heavy metal band, Tenacious D, and looks as unlike a rocker as you can imagine, being bald, fat and middle aged. The two of them team up to create rock history, but decide that the only route to stardom is acquiring (stealing) the guitar pick of destiny, which is forged from Satan's tooth.
Cameo appearances from Ben Stiller and Tim Robbins can't disguise the fact that there is a large empty space where a plot should be, as well as a ten mile Mirth Free Zone. In fact it's a waste of time and money.
