One of the most exhaustively-researched biographical documentaries I've ever seen, and nary a moment of its two-plus-hour runtime is wasted. Packed with honest, revealing, enlightening face-to-face chats with every major player in Bob Marley's story, this candid tell-all effectively captures the social impact of his work on-stage and in-studio, along with the intimate details of his private life. It doesn't take much prodding to realize that before we can fully comprehend one, we must also understand the other.

Dedicated apostles of the icon should welcome the personal insights, while more passive appreciators are bound to be staggered by the power of his voice on multiple levels - musical, political, religious and intellectual. Warm, complex and genuine, just like its subject - I can appreciate his work on a whole new level today.
