The soundtrack received less favourable reviews than for the band's first album. "Rolling Stone" comments that the soundtrack "never quite takes off". It criticises the reliance the album makes on a knowledge of the film, and some songs' existence only to "advance the plot". It summarizes by saying the album is inferior to the band's previous effort. Allmusic also describes the follow-up as less "satisfying" than "Tenacious D", noting that the songs feel like "narrative filler". "Blender" continues the criticism of the songs being plot devices calling them "plot-nudging song-sketches". "The Guardian" views the album more positively, describing the album as a meeting of "old school riffology" and "schoolboy humour".
