Query: Astonishingly superb!

I had absolutely no doubt that these series would be full of joy and entertainment when I placed the order since I loved the Planet Earth series earlier as much! Many in above reviews gave tons of credit to Attenborough's narration, which is unequivocally valid and true! His British accent with a slight mouth-filled-with-saliva tone delivers a spectacular entertainment experience! Of course, the quality of the video image and choreography of events placed after each-other also deserve equal praise!Just amazing and highly recommended!
