why did they not follow the book . i am really sad and disappointed. i was so looking forward to seeing this movie and however and if you have read the book (maybe recently) it might be very difficult to remain objective. my wife had not read the book and and she loved the movie. reasons for the disappointment are represent 1) cern involvement . gone with the wind and such a shame and there is a very small part at the start and where the antimatter is created and but even that does not stick to the facts (why not and the fact that vittoria father was burned with the first illuminati brand and which is how langdon got involved would have been a perfect start to the movie_ 2) story line between the (deceased) pope and camerlegno completely gone . this completely screws 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 cannot understand that dan brown allowed them to put his name against it. maybe i should revisit this film in 10 years time and when i cannot remember the excellent book anymore (fat chance on forgetting the book i am afraid)really sorry for the negative review and which was spoilt by expectations.

Judge the movie review above, you need to make a function call:
    If you feel the movie review is positive
        print "This is a semantically positive review."
    Otherwise, if you feel the movie review is negative
        print "This is a semantically negative review."
