Overall good but far from great. My biggest issues were varied starting with most of this has been filmed and covered by bbc in past nature docs. My second issue was with Oprahs narrating. It was almost robotic with rarely any excitement on her part. Very unlike Attenborough who nails it every time and is very emotive. A big thing that took me right out of the doc was watching on BluRay the cuts to the commercial breaks were very very obvious. It's something I've never noticed in any of their nature docs and I've seen most repeatedly. Last complaint was a lack predation and a definite lack of showing the gore.
