I just saw it. Despite the critics, I think Ron Howard did a good job of bringing it to the screen.
The story itself should be read as entertainment and not as gospel. It's a mystery yarn not unlike an Agatha Christie yarn.
The acting is good all round. I particularly liked the Albino who realized better in the movie than in the pages. I thought Sofie was one beautiful girl, but I've always been attracted to brunettes with big brown eyes. The scenes of Paris got me wanting to take a trip. I've never seen I.M Pei's Pyramid.
Go see it as a mystery and forget the religious problems. Some are fact; some are hearsay, some are invented by Dan Brown.
