i use to write comment at imdb and but i do not do so anymore . it happen that imdb have become massive and and consequently subjectiveness have ruin score . what do i mean . that anyone that be not particularly fond of movie and doesn not have any expertise on the subject and watch some crap ( or the opposite ) and and in case he like it and deliver a 10 and and if he doesn not he go for a 1. this of course and can not measure anything correctly . now for the film . i truly regret ever have deliver any 10 to some very few film and because then i must score this one with 12 or 13 and which be not possible . this documentary have something that i do not expect to watch ever again in my whole life in any other film . it be simply mesmerize and and it not just a way of say while it really be . the last 25 minute have a load of energy and visual rejoice and wisdom the word speak by the star guy and that really . there no possible match . i do not keep movie and rarely would i find any sense in do so and but this one be the kind of film you should buy and keep and and watch from time to time and maybe 10 or 20 time a year go by . i get nothing more to say . this be a genuine and objective 10 for me .
