Your thoughts on 'The Da Vinci Code' Book and film?

The mystery part of the book/movie was the best part...the theological "facts" he tries to use are erroneous and the main one that he introduced in the prologue/preface of the book was declared a fraud in the French courts back in the 1960s- which Dan Brown knew about and had subsequently ignored in any interviews given. So, thumbs up for the mystery, thumbs down for the theology.
