this be a qualified positive a the first hour or so of this documentary be great and the last half hour and or or the 90 minute total length start to put me too sleep . i mainly give it a 10 because i be amaze at the technique use in this film and fantastic animation and music and great sense of humor and editing and these be thing i do not usually notice in a movie . the filmmaker must have have a huge budget to make this film . i hope some day she do a tv series a she be truly an innovator . i think the first hour be magical . the filmmaker be an excellent narrator and her narration be great . but after about an hour or so and i start to fall asleep and i think the film maker have the potential to be another orson well if she learn pace and that more be not necessarily well and figure out that an hour of stimulation beat an hour of stimulation and a half hour of boredom .
