input:  Now, answer this question: Title: THIS BOOK IS FALSE. Review: I'm summarizing another review on here, because it seems like most of you guys would rather skim the important negative reviews, then turn right around and still give the book five stars.Didn't you see?!? Those socalled "well researched factual ideas" ARE NOT TRUE. I hated the book just because it was written badly, but now I know that Dan Brown LIED, hoping that you guys would do what you've done and think that he was telling the truth.This is pathetic sensationalism, and you guys bought into it.
