Mini-Review: It's not a 'great' film and the reasons are plentiful. The acting is terrific but the characters are quite dull. A similar thing happens with the music (which obviously carries an important role with Cheyenne being an ex pop-star): the songs themselves are great and suit the vibe but they're played over and over. I simply expected more. Final verdict: Not memorable were it not redeemed by the fine imagery and camerawork.
Mini-Review: Perhaps it started out too slow (by fully explaining the event), but it captivated my interest nonetheless. Call me biased, but there's not much that Werner Herzog does wrong...
