All the trickery and disinformation that Brown threw at us was a bit annoying, to me anyway. It was an over-the-top illusion on such a grand scale, but then again, that is the point, to show how powerful and deceptive The Consortium is. I think really what I like/enjoy most about Brown's works (and I've only read two), is his historical and locale descriptions. His detailing of art, architecture, historical facts and icons, are breathtaking and always make my artistic-wanderlust-soul, yearn to visit every place, see every building & piece of art he describes.
I did dig the plot, the overpopulation, how we're over consuming natural resources, water shortage, reducing fish from over fishing, letting species of animals and flora & fauna die out, the destruction of precious, and vital, ecological wetlands, forests and jungles, and so on. That's all a very real concern worldwide.
My only criticism really is, his storytelling is mediocre. I felt that way with Da Vinci Code as well. He writes short, fast-paced information filled chapters that end with cliffhangers, which make the readers "HAVE" to read the next chap just to see what happens. This also makes for a very quick read. Overall, I enjoyed & liked it. I would give it a rating of: X1/2-XX (out of a XXX rating system) Leaning more towards the X1/2.
