Sebring has no interest to explain Patti Smith, to interpret her life and work or to narrate biographical events in chronological order. Instead he presents a manifold mosaic of visual fragments and music together with permanent autocommentaries. The result is the intimate portrait of a remarkable artist that shows a lot of private (and vulnerable) sides as well as an angry political person.
This isn't the whole story of Patti Smith, just a snapshot, a sweet little visual poem. She gave the best rock n' roll show I ever went to! And I grew up during the rock n roll era, 60's/70's. Here is a taste, a live recording from WBAI 1975, :When the Hunter Gets Captured by the Game" hope the link still works :-) https://www.youtube.com/watch?v=sOIuFbrHx24
As a doc, it has no strenght, but as a portrait of her day-to-day life it's very appealing. Naturally, it could've been more investigative (I missed more Chelsea and Robert stuff), but watching Patti Smith, part woman, part God, talking about her life, memoirs and Art, is never too much. And the movie brings some nice live performances and some beautifully shot scenes-- those on Coney Island were really something.
