One of the great talents of her or anyone else's generation gets the royal treatment with this superb two-hour (with bonus material) documentary. It's all here (via interviews, including conversations past and present with Mitchell herself, photos, generous helpings of concert footage, and more): her Saskatchewan childhood, her lovers, her painting, her reunion with the daughter she had left behind at age 19... and, of course, her music, the songs, recordings, and performances, so intensely personal yet so universally accessible, that comprise one of the most extraordinarily original and significant (if not always wildly popular) bodies of work any artist has ever produced. Even true fanatics are likely to find revelations here; the rest of us can simply rejoice in the life and artistry of Joni Mitchell. The extras are highlighted by complete concert readings of four songs, including "Big Yellow Taxi" and "Woodstock." --Sam Graham
