5 Fantastic picture quality! Very entertaining series!reaktor24 | 07/03/2011 | See all reaktor24's reviews (7)Simply amazing. The picture quality is absolutely breathtaking! There is so much detail in the picture. It is probably the best looking blu-ray I own (and I own loads). This is probably even better quality than Planet Earth which is also very detailed and sharp. This is a quality series with some incredible human stories and bizarre rituals from tribes around the world.@Budda1The picture is 1080i like Planet Earth because that is how it is broadcast by the BBC. This isn't a movie, its a documentary! 1080i is better suited to documentaries. See this extract from a web article:"1080i: 1,920x1,080 pixel resolution. High-definition picture that is displayed interlaced. Each odd line of the picture is displayed, followed by each even line, and the resulting image is not as smooth as a progressive feed. 1080i is therefore a more detailed picture suited to documentaries and wildlife footage, but less suitable for action-oriented material such as sports and movies."
