"I'm pissed off about everything in general," says Kurt Cobain in the taped interviews that form the basis of this worthwhile documentary portrait of the artist. Behind a montage of many, many establishing shots of Washington state locations and faces, the King of Self-Pity describes his childhood, his emotional and physical pain, life in Aberdeen, Olympia, and Seattle, why he hated journalists, and more or less how Nirvana reshaped punk rock into grunge and snatched the pop music gold ring in the early '90s. Thanks to director A.J. Schnack's rhythmic procession of 35mm images, Cobain's words seep into context in a meaningful way. Nice work by DP Wyatt Troll and still photographer Charles Peterson (97 min., 2007).
