I have yet to read the DaVinci code, but I am yet undecided on whether or not it is worth my time to read after viewing the trailer (Just look at the graphic nature of the movie). The trailer contained action cliche after cliche (sorry for the non-accented e), and Ian McKellen reminded me too much of Gandalf to be anything but humorous. While the book was definitely popular, a recent trip to a forum discussing the Name of the Rose indicated that those who read both found the DaVinci Code much too simplistic in comparison. So I don't know, I shouldn't make these snap judgements, so I think I will sleep on my decision to read the book, and then to make the decision to see the movie.
