The New Yorker has a good article about TDVC and Sony. The New Yorker is one of the most relentlessly-secularist publications in America, so it's significant when you see nuggets like these in its pages:
Dan Brown's best-seller was now under steady assault, its theology attacked by a series of books bearing titles such as “De-Coding Da Vinci” and “Breaking the Da Vinci Code,” which deconstructed Brown's scholarship and convincingly refuted many of his key claims (such as Christ's divinity having been decided by the fourth-century Council of Nicaea, on a close vote). Brown's art scholarship was also broadly assailed. The Times published a critique of “The Da Vinci Code” by the Renaissance art expert Bruce Boucher, who gently mocked Brown's “shaky” grasp of the historical Leonardo (pointing out, for example, that the artist's name was not “Da Vinci”). Boucher concluded his article by suggesting that “The Da Vinci Code” might make a better opera than a film, offering the old advice that “if it's too silly to be said, it can always be sung.”
The article as a whole is highly interesting and worth reading (or at least skimming).
