The DaVinci Code SUCKS!! It's terrible, poorly-written trash! It made my eyeballs bleed to read it!! My wife read it and got sterile!!!!! A man came and took away all my beer for reading it!! I can't overemphasize how BAD THIS BOOK IS!! IF YOU EVEN THINK ABOUT READING THIS BOOK I WILL HAVE NO CHOICE BUT TO SHOW UP AT YOUR HOME AND SLAP YOU ACROSS THE FACE UNTIL YOU AGREE TO DO PENACE AND RENOUNCE NOT ONLY THE BOOK BUT THE AUTHOR, PUBLISHER, PUBLICIST, PROOFREADER, AND THE COMPANIES THAT MADE THE PAPER AND INK USED TO WRITE IT!!!
Roger Ebert put it well... "The Da Vinci Code is a book to read only to come to the conclusion that life is too short to read books like the Da Vinci Code"
Or as Office Barbrady from South Park would put it:
"Yes, at first I was happy to be learning how to read. It seemed exciting and magical, but then I read Da Vinci Code. I read every last word of this garbage, and because of this piece of s**t, I am never reading again."
Sounds enticing but I still ain't interested.
As I understand it, not actually having read the book, the concept is at least interesting. Historical mystery tied into existing legend; adds verisimilitude (hence so many getting sucked into believing it is real). The central figure, Jesus, is the most significant historical figure in the world, so people are always fascinated by him (one way or the other), and the story being believable enough to at least think to yourself "gee, what if...", makes it a winner. I may watch it, if the script is decent. Quite apart from the totally fallacious "facts", it makes for good storytelling.
Dan Brown's, and possibly all of literature's, utterly worst novel of all time is Digital Fortress.
Remember that giant space robot vacuum cleaner from the movie Spaceballs? That's how much it sucked.
