Thanks for the tip, CH! I watched this over the last three nights and found it really engaging.
At first I found the running time a little off-putting (he's not an artist for whom I've ever felt much passion) but soon after I started watching it, I realized that giving it 4 hours is the film's greatest strength. Not only can they do justice to telling the story of his/their long career but it also gives plenty of time to let you watch the band play the songs! Huh! What a gift. (American Girl just kills.)
It's also nice that each chapter of the story can be told visually, be it through home movies, vintage TV performances, MTV clips, etc. The only thing glaringly absent is more detail about his marriage... he got married young, right before leaving Gainesville! But you gotta respect him for keeping all that private stuff private.
With Bowie and Prince in mind, it feels good and necessary to appreciate a living legend before he becomes an ex-living legend. The film is ten years old so I googled him, nervous about how his last decade had gone. Seems he's doing just fine, and better yet... this just came out! Inspired by the doc, he got the old band back together. What a class act.
