The Movie or the Book

So I find myself reading Dan Brown again. 'The Da Vinci Code' was the movie that got me interested...then I read the book. OK. So now I see why they say 'the movie was good, but the book is definitely better!'
Then I read 'Angels and Demons'. Same thing!! You gotta read the book! But alas! when I say read, I actually mean listen. I am the world's no. 1 Audio Book fan. This blog is meant for sharing views on "THE MOVIE or THE BOOK?"
