I'm new here so I'm going to go ahead and add my opinion eventhough I know there are pages of discussion before this.
I'm not sure what the tone of this thread is, but I imagine it doesn't put Dan Brown in the best light. Anyways, here is what I felt about The Da Vinci Code.
One of my old roommates bought the book soon after release and loved it. He went on to buy the other Brown books, and I decided to give his books a try. For some reason, I have this thing where I like reading an author's books in publishing order, so I told myself I would read all four Brown books with TDVC last.
I started off with Digital Fortress. Not a bad book, pretty entertaining, but average at best. A couple twists suprised me and I went on to Deception Point. I felt it was a little better, but quickly realized the same plot twist occured. I then went on to Angel and Demons which I didn't care for all that much. By this point I figured out Brown's formula, and there were no real suprises.
Finally I read TDVC and honestly I enjoyed it. I thought it was a fun read, and one that I knocked out pretty quickly in an afternoon. I think the plot will make for a good movie. That said, I'm also a bit curious on why the book is so popular. Sure its a fun thriller, but its also the exact same plot as the other three with a different setting and such.
