Lesson of Darkness is really cool. It's more like a meditative art piece than a documentary. I really liked it. I remember Herzog shot it from the perspective of an astronaut discovering an alien race on an alien planet.

It's just the aftermath of the Gulf War where they began burning the oil fields and it looks like something from a sci-fi. There are haunting interviews with the victims of the war. It's truly such a beautiful film that you just take in and experience.
