I personally liked the book more. The movie just fucked up with saving one of the cardinals. The only thing I didn't like in the movie or the book was a helicopter scene.
I like Howard, and Hanks ... but I was let down with Da Vinci ... and I skipped this one so far ... I'll catch it next week if I'm bored, and don't wanna do a re-watch of T4.
I've read all of Brown's books, but I was unaware that the movie was out already. I actually never saw The Da Vinci Code movie either. I'll have to catch this flick after Terminator. 8)
