I'm still pondering my opinion of THE DA VINCI CODE.  It was like the girl with the curl:  when it was good it was very good.  I agree with DR Maria:  too long, and since there was a bit of abridgement of the book and the removal of one character at the end, I think they could have abridged a bit more and cut 15-30 minutes.  I loved the first 90 minutes
My friend Mr McKellan was wonderful, and gave the show a big kick when he took over.  I did think some of the narrative visualizations a tad campy, and would have preferred the narrative plain, as it is in THE MALTESE FALCON.  
Overall, I gues the film, like the book, is a good amusement park ride, only it goes a bit too long.
