Slightly flat, but if you read the book.... - The Da Vinci Code Reviews

The film stays about 95% accurate to the book. That being said, the book is a lot of conjecture and puzzle solving which leads to lots of dialogue, which could be the most fascinating points of the movie, but they do fall a little flat. The action is mediocre. I cannot speak for those who did not read the book, but for those who did, it doesn't seem to be the kind of story to translate REALLY well into film. It's solid, but not amazing. Worth seeing though. (Spoiler below) the whole thing about "the well" and the claustrophibia - made up entirely for the film, seems to be a kind of way to say "hey christians/catholics, see we still think it's ok to have faith." Its a decent addition but still feels very forced after reading the book and all the information absorbed beforehand in the film. For those who argue its a work of "fiction"...well we all know how well researched the book was, and therefore (Brown) sued over. The topic itself is fascinating of you allow yourself to play "devil's advocate" and go in with an open mind...
