Query: Poorly researched garbage

I can't believe I read the entire thing. But with my time invested, I had to see how it ended. The plot is so outlandish that suspension of belief is impossible. Surely no one could take this book seriously. But there are all of these stellar reviews...Even if the book were a bit more plausible, there's the hackneyed writing to wade through -- hackneyed because Brown and his publisher spell out every last aspect to the story; nothing is subtle, nothing is left to the imagination. Brown either does not trust the reader, or he is simply inept. When one considers the single dimensional characters standing in for some of the sharpest persons on the globe, this reader cannot help assuming the latter.What garbage. Save yourself the trouble.
