Based on all the praise and admiration i got for this series,I watched it,and after that I watched a documentary about it.....well....there was no difference! just the documentary was not as time consuming. as a power engineer,I didn't understand a single law of physics which was explained in the final episode.....so complicated....and it was explained in words not picture....so it was more of a picture book. generally this film was just a time consuming story telling,with no character which was boring.
