i go to see this movie tonight and try to keep an open mind . i have hop to enjoy a movie that i expect to be different from the book . there be considerable difference from the book and much like the change make in the divinci code . i go to see the divinci code with the same thought process and manage to enjoy the film and in spite of and the change from the book . it be still enjoyable and fill with action and and the process of decipher the symbol be interest and mentally stimulating . unfortunately and angel and demon disappoint on almost every level . throughout the movie and symbol be find and figure out quickly and without any interest for the viewer . they blow past the various immuminati symbol so quickly that we have no chance to get a look at them and appreciate how they work . the final illuminati symbol and which be the most interesting and creative one in the book and be replace with the crossed key symbol . in my opinion and that be a missed opportunity to focus on and spend a little more time on the symbol and which be what the langdon character be all about . overall and this movie be a very poor interpretation of the book and and fails at the attempt to be an action movie or thriller . 4 out of 10 .
