Query: Why is this book so popular!?

I refused to believe all the hype about this book for a couple of years until just recently I finally picked it up. Wow. I was disappointed. The story itself is provoking and brings up some interesting points, but overall it is a cheaply written thriller.There are much better, more interesting thrillers by Michael Crichton and the likes. Overall I would compare this book to a cheap action flick, one that causes you to laugh at the shear audacity of many of the scenes, laughing, pointing and saying "Hey! That could never happen!"In conclusion, if you like books you probably won't like this one. If you prefer reality TV then you will love this book. Blah.
