Da Vinci Code = Fiction
When people read it, they know what they're reading and are there for fluff and entertainment - I don't anticipate that people who read it actually think they are getting an historically accurate, theological lesson.
The Vatican has asked for a boycott of the Da Vinci Code movie. This, to me, is one step removed from the whackjobs who said that
Harry Potter was inappropriate for Christian children, and this is equally insulting to my intelligence.
Don't get your panties in a bunch over a preposterous book that makes preposterous claims (albeit in a very entertaining and page-turning fashion). I love when people call for boycotts of books and movies...it really hurts your organizational credibility - what are the implications of a Catholic watching the Da Vinci Code? Most likely nothing. Perhaps uptight Catholics won't enjoy it because they'll be busy picking at the factual innaccuracies - watching it as a documentary as opposed to a light popcorn movie. Try to deconstruct another light popcorn movie - say X-Men 3 - the same way. You'll sound like a complete douchebag...which is exactly how you'll sound deconstructing the equally fictional Da Vinci Code.
Dan Brown = Tom Clancy = John Grisham. I don't really believe a lot of the claims and technologies discussed in Clancy's books, although there is a shred of reality to make the story realistic. One shouldn't believe a lot of the claims in Brown's books either, despite the fact that there are droplets of reality within the buckets of nonsense.
Apparently Vatican officials aren't the only ones who don't want you to see the film. I probably won't see the movie, and if I don't,
it won't be because of a Vatican boycott.
