ok. on the whole and this three part documentary will bring most interested people up to date with go on in the world of physic and and the last 300 year of discovery of our universe . if you have read stephen hawking brilliant book a brief history of time and understood it then you might benefit from the visual description of certain concept . which i do to a certain extent . greene be bearable and but obviously for the sake of the mass and tend to explain thing in a slighty patronise way . this be of course deliberate and will be perfect for almost everyone who watch this series . the guest scientist be good . ( no hawking and but i suppose he have his own dvd ( s ) ) i keep wait for him to appear but they rotate through the same one for almost 3 part . ( very american weight here and with a few brit and one antipodean ) i buy the nova 2 disc edition ( ntsc ) and there be a few inclusion that really detract from the overall experience . 1. the this be bring to you by . at the start of each part be a necessary evil for the first part and but see it 2 more time before it be over be very ordinary . 2. can not be help i suppose but there be quite a bit of overlap at the start of 2 and 3 which have me reach for the ffw button a few time . 3. this disc set be straight from tv . ( ie ad and what happen last show for those that miss it and and frequent goto pb . org for more . ) appear throughout the presentation . ( quite unlike bbc material which be unmatched for presentation . planet and the blue planet and etc ) my positive be base on content alone . the niggles be there but i get over them . if this have have be do with that classic british accent presenter ( you know the one ) it would be a perfect disc set in my opinion . if you have see this and want more . then i highly recommend hawking book a brief history of time . i wish it be a movie too . happy viewing .
