We went to see "The Da Vinci Code" opening day at a local theater. We got there way early because we thought that it would be mobbed. Guess what? The theater was virtually empty! I mean I'd be surprised if there were 30 of us in a theater designed to hold three or four hundred. After I saw the film, I could understand why --it sucked!
I never read The Da Vinci Code. But I did read "Holy Blood, Holy Grail" back in the mid 1990's. HBHG had me on the edge of my seat until they hit "the punchline" -- that "Mary Magdalene & Jesus Christ married & had kids" -- then it was a huge "Ahhhh No!!!!", because that's just too stupid for words.
And yet, I've heard people I know go on & on about The Da Vinci Code as though it's valid theology and I just keep thinking to myself, "Are you nuts -- or just stupid?"
I still have a tattered old paperback of that kicking around somewhere - there used to be someone on the old Time Pathfinder boards who believed it as Gospel, so when I saw a copy at a library booksale, I pounced on it and read it. The authors needed a LOT more tinfoil. You know they sued Dan Brown, right? I never heard how it turned out.
DVC was totally ripped from HBHG. I think there was even a lawsuit about it. But the HBHG authors lost, if I remember correctly.
