Davinci Code Foolishness

Many folks are taking the Davinci Code's allegations as true without really considering how valid its claims may be.

• Dramatic fiction books in this genre are written for amusement, not critical thinking. People who buy them want to suspend disbelief, and take their mind off of everyday tedium, not understand serious issues. "Amusement" by the original definition is distraction from thinking, and The Davinci Code certainly meets that definition, but does it successfully say anything worth thinking about?
• Many plot turns in Davinci Code are based upon total incompetence - unlike most very successful drama fiction. Examples: the first big scene involves a killer of incredible skill on his fourth victim for the night - but he forgot to reload his pistol after the first three victims? Every police type semi-automatic pistol remains open after the last shot is fired, so magazines can be changed in a hurry, yet this skillful killer manages to "click" his Glock 17 shot semi-auto pistol on an empty chamber. The big murder victim in this scene is the head curator for the Louve musem, whose primary role includes ensuring that benefactors successfully pass donations on to the musem - but he does not believe in written wills? A key character is a police cryptologist - who has forgotten simple cryptographic puzzles she solved as a child? Another key character is an expert in ancient historical documents - who believes in Gnostic documents with anonymous authors claiming to give narratives from key persons in the life of Christ but which were actually written over a hundred years after the last such persons died?
