Good review ! I cannot watch anything made by Herzog, but I thought, a documentary about a cave, well, maybe this one is different. It is not. It is the same drawn out, boring and depressing crap as everything else he has ever made. He should have at least hired a professional narrator, because his voice is so lifeless that you rather watch the entire thing with the volume off. What do we have here ? Paintings of animals in a cave discovered and fully explored 17 years. That means, we are not discovering anything here. There is hardly any material to fill 90 minutes, unless, well, you search for mankind's weirdest spirits and have them comment on what the cave shows. Wagner, opera, what the heck ? I still only see primitive drawings of animals that lived there during that time.Herzog belongs in a Bhuddist monastery, where he can sit and smoke pot for the rest of his life. That is probably what he has been doing anyway up until now. I do not see why he ever decided to pick up a film camera. Please do not let him near one, ever again.
