So, I chose the Blu-ray of AMAZON to watch this afternoon. Very enjoyable 40-minute film, but the shots of nature in the region were just too brief. One longed for the intensity and depth of a PLANET EARTH episode.
The Blu-ray was, of course, spectacular, and unlike PLANET EARTH, the AMAZON disc had a DTS-HD MA 5.1 surround track which was mesmerizing.
