I read Da Vinci Code by curiosity and I'm sure there are many like me. You know that's very touchy to affirm Jesus was married and with Mary Madeleine ! Catholic church lost many believers during centuries and a publicity like Dan's Brown book and movie is not a good thing for their efforts to keep people under control. I must admit I have no respect for those who accepted an ex SS as a pope. And I cannot forgive them for all the crimes during the inquisition period. You have the right to say what you want about Dan Brown, but I cannot cry for chatolics church having problems dealing with.
It's an easy reading, like all the Sandra Brown.
I read Angels & Demons, too. The best of Dan Brown's is Digital Fortress.
I saw a few episodes of "Les Poupées russes". I'm afraid I have no patience any more for series.
Those who want quality, read Eco. Those who want an easy lecture on the buss or metro will have someone as Brown.
