Karl von Randow’s review:
The paintings are amazing. I have wanted to see these cave paintings for years. It's incredible that the film crew were able to film, and their footage is beautiful. Depending upon your mood, and perhaps degree of sleepiness, the multiple repeats of the same paintings will either make it epic or start to drag. For me it was the later; especially the 10 minute requiem at the end - passing over all of the art again with just a music track.
