This set is the reason I got a 4K Player - I wanted this great content delivered to my 4K TV in all of its glory, uncompressed instead of streamed content. The footage itself and the quality is Amazing! Nature, Landscape, and scenic movies shine with UHD / 4K content, while basic movies containing a lot of dark scenes can be left to be streamed (and compressed) quality. It is great to see such content in 4K / UHD;! Sir David Attenborough continues his amazing work and is a guiding compass of the great series. Mr. Hans Zimmer musical work does a very effective job from capturing the audience from the first second the Disk Menu Title loads and continues to do so until the end. LOVE IT! It is great to see such content in 4K. Looking to purchase Planet Earth 2 .
