Which one do u like the book version or the movie version?

I read his book Da Vinci Code. My motivation to read his book is because of the controversy relating to faith. So, I decided to read, I read it only in a day. The way he explores the story is very unique. He can combine the complexities of history with suspense and ends with a big question in each chapter. The sad thing is when I watch the movie version...hmm, I feel disappointed because all of my imagination becomes flat end in the box of movie. Some says that movie blocks our imagination. So, how do you think? Which one do you prefer movie or book version?
