Hype! is a documentary directed by Doug Pray about the popularity of grunge rock in the early to mid 1990s. It incorporates interviews and rare concert footage to trace the steps of grunge, from its subversive inception in neighborhood basements, to its explosion as a pop culture phenomenon. Hype! shows grunge from the point of view of people within the grunge scene, and attempts to dispel some of the myths of the genre promulgated by media hype, hence the title. The movie generally portrays the latter faction in a satirical way, though acknowledges that media hype helped to propel some of these obscure bands to fame, albeit briefly.
