this series have a lot go for it with beautiful footage of the some of the most impressive underwater environment on this planet . be a staggering five year in the making and one would be hard press to expect any less . i do get the impression that some scene from the first episode where repeat in the latter one and which be naturally only a minor gripe . david attenborough be great a a narrator and comment be informative and leave enough room for one imagination and and well space out and so that viewer get plenty of time to reflect upon the breathtaking imagery . if you get the opportunity try not to watch a translated version of this series . a definite must see for anyone interested in the intricacy of our blue continent and easily the best documentary on this subject i have ever see .
