For those who read the book, the movie will probably be a dissapointment. Its always like that.
I couldn't put the book down myself, it was a great read, and its a lot of fact mixed with lots of fiction.
You have to keep an open mind and realize it is mostly fiction.
Unless you want to beleive that Mary Magdalene wasn't a whore and she was Jesus' wife who bore him a child, which happens to be the "vehicle", The
Holy Grail.
