5/5 It IS different
  by I. He (Redwood City, CA, USA)
I bought this because I borrowed my friend's DVD version of it, after viewing two discs, I decided to own one. The blue-ray version of this is better than the DVD counterpart. I had chances to compare the DVD one and the Blue-Ray one side by side, it IS different. Now, whenever friends come by, this is the disc for me to show off the big screen TV. I never heard people saying any negative words about this serials, everybody was impressed by what the mother nature has given, everybody has always their astonishing mouth opened with the 'wow...', highly recommended it, and thanks BBC to make this excellent contribution to the world.

5/5 Amazing

Simply amazing. How they shot this I'll never know. Even my 13 year old was in awe.

4/5 very good, but

Most people break their reviews of this product down in 2 parts, picture and content. I think this dvd has been praised very highly due to both but even more so concerning picture quality. It is extremely popular for "Jaw-dropping" detail, visually.

The content is great and yes, the narration is superb. Sounds like he should be narrating Lord of the Rings or something. Very, very interesting so far. I have viewed a disc and a half so far. I will update when I finish watching. The exploration is fantastic (most shots are by helicopter it seems)and the history is splendid. I am learning so much. It is very much about the history and learning about the world. I love the strange and bizarre creatures that I never knew existed. So far, the animal "hunts" are very tastefully done. I am not a fan of seeing animals suffer (even though it is nature). Just the knowledge and experience alone is well worth this package.

The picture I found to be slightly disappointing. It is recorded in 1080I. Being a Blu-Ray, I expected 1080p. Expect the detail to be exactly like watching this on Hi-def tv broadcasting (on Discovery channel or something). There is some grain here and there, and from what I have been experiencing lately with a lot of Blu-Ray's, is that the detail is subject to light. In dark scenes the picture will look average with some grain and blurriness, meanwhile with scenes of natural sunlight the detail will be incredible. Every now and then there are scenes with great lighting and detail that make me go "Wow". But it is not uniformly throughout the entire dvd. Your not going to be sitting down the whole time with your mouth open. More of like an open-closing sort of thing.

Another thing I noticed was the contrast flickering. In some episodes the contrast seems to go in and out like a pulsing set to every second. I noticed this in dark scenes and found it to be VERY distracting. I haven't checked other reviews for this, but I find this extremely unacceptable.

For what it is worth, it is a good buy.

Viewed with a Sony 1080p lcd tv and slim ps3.

5/5 Earth like you've never seen it before
  by Shyam Sundar (Seattle, WA USA)
This is one of the best nature documentaries that I've seen. The equipment and some the AV techniques used in Planet Earth is unmatched. David Attenborough's narration is intriguing and crystal clear. I agree with other reviewers that every home should have a copy of this spectacular documentary production. I haven't even got to Earth: The biography but I already have my money worth just with Planet Earth.
