‘Janis: Little Girl Blue’, directed by Amy Berg and narrated by musician Cat Power, is an insightful documentary about the singer-songwriter that draws on letters between Joplin and her parents - some made public here for the first time. An intelligent portrait of a Texas teenager’s evolution to stardom and her battle with alcohol and heroin addiction - Janis Joplin emerges from Berg’s absorbing documentary as a true maverick and a formidable talent. ★★★★ "Eye-opening account of Joplin's brief, fierce life" - Peter Bradshaw, The Guardian
