(Spoiler Alert!)
I enjoyed the book for the symbiology stuff & its relationship to Western civ.
The rest, though, seemed supremely hokey. Since I'm not Christian, I wasn't really offended, though I can understand why Christians would be. (Had the subject been Islam, Hollywood would have never touched it.)
The part about that French girl being a descendent had me rolling my eyes in disgust, if not rolling on the floor laughing. It smacked of PC more than blasphemy.
Brown's book ANGELS AND DEMONS was almost as ludicrous.
Yeah, it's pretty hard to build an underground bunker big enough to construct mammoth sets and shoot a whole movie.
