I came to like Dan Brown after reading Angels and Demons, then on to Deception Point and Digital Fortress. What Dan Brown does in researching all the information he lacks in filtering what is truly necessary for the reader to absorb. In order to unlock a mystery we don't need half of what Brown throws at us. For example he goes on and on about the meaning of word and then juxtaposes that with the symbolism of the word then mixes it with the different interpretations of the word. At one point during my reading I felt like I was being lectured rather than entertained by the plot elements, which lets be honest were severely in short supply in this latest Langdon saga. That's right saga, it just kept going and going. I honestly wish Brown's computer would have crashed 3/4 of his way through this novel and just given up writing this one all together. The last two chapters of this book where Robert and his latest *love interest* babble on seems like Brown took the last bit of his research notes and threw them into idle chit chat for our benefit. BLAH!!! 
 *(that's right latest love interest, not only is there one woman dumb enough to fall for this boring guy, we can't forget that there were 2 ahead of this little starlet). Let us not also forget that one of these damsels was the direct descendant of Jesus our lord and savior. Just like her ancestor and his infinite forgiveness she put up with his constant yammering. Apparently she also had a sick dog complex and felt sorry for Langdon as well. 
 Moving on, Brown seems to have lost what he originally had talent wise. This novel follows the same scripted formula. Talky talky, run away from danger, hide, more talky talky, get caught, escape narrowly, then rinse and repeat!! In my honest opinion I believe that Robert Langdon is becoming less Indiana Jones and more Mr. Magoo. Time to put your type writer in the attic Mr. Brown!
