James Pinkerton offers a sympathetic take on the movie in this article.
Indeed, a book/movie this immersed in Christianity -- or, if you prefer, anti-Christianity -- can't help but get people thinking about Larger Things. It's said that some 45 anti-Code books have been published; does anybody think there would have been that much popular scholarship devoted to origins-of-the-church controversies without Dan Brown's provocation? And what about all those websites, each one a labor of agape?
I will bet that "The Code Controversy" is going to be remembered as a turning point in popular-religious culture. Christians flocked to see "The Passion of the Christ," which changed Hollywood, but then, two years later, they flocked to react to "Code"; they have created their own counter-culture, which will bear faith-fruit long after this particular movie is reduced to third-tier DVD-dom.
