It was not a great work of literature. It was going to be a tall order for it to transform into a great work of cinema.

Especially when the lead in this movie hit his acting stride with Peter Scolari in this show.
I felt that while reading the Da Vinci Code that that author was trying to write a novel that would be made into a movie. I actually like some of Dan Brown's other books better.
I thought that the movies The Godfather and Jaws were good adaptions of the books. Actually, Jaws the book had some interesting plot details that did not make the movie (mob connections and affairs).
