The Da Vinci Code by Dan Brown and the new film version from director Ron Howard are serving as inspiration for bloggers: the blogosphere is absolutely on fire about both. The posts have been increasing in the lead-up to the film's opening today. Not everyone is excited about the film. The film has been criticized by the Catholic Church and other religious groups. Opus Dei even started a blog to battle errors they believe are found in the book and film.

The controversy about some of the elements in the book -- especially about Jesus Christ and Mary Magdalene -- are part of what is driving the blog posts. As anyone who has ever moderated a web forum or blog comments will tell you, there is nothing that starts flame wars like religious discussions. People also love the codes and secrets contained in the mystery novel.
