why do they not follow the book . i be really sad and disappointed . i be so look forward to see this movie and however and if you have read the book ( maybe recently ) it might be very difficult to remain objective . my wife have not read the book and and she love the movie . reason for the disappointment be represent 1 ) cern involvement . go with the wind and such a shame and there be a very small part at the start and where the antimatter be create and but even that do not stick to the fact ( why not and the fact that vittoria father be burn with the first illuminati brand and which be how langdon get involve would have be a perfect start to the movie_ 2 ) story line between the ( decease ) pope and camerlegno completely go . this completely screw up the motive for the stealing of the antimatter 3 ) story line between langdon and vittoria vetra completely non existentall in all and too flaky storyline and and can not understand that dan brown allow them to put his name against it . maybe i should revisit this film in 10 year time and when i can not remember the excellent book anymore ( fat chance on forget the book i be afraid ) really sorry for the negative review and which be spoil by expectation .
