Bests & Worsts Reviews from Amazon

I don't understand why this book is so highly rated. I belong to a small book club that chose to read it adn 4 out of 6 give up on it. Those that finished were very frustrated. Not only was this book too long, it was unbelievable due insufficient character development. Things just sort of happened around people and they "changed" (not evolved) from chapter to chapter. There are many books I've not liked, but I have this crazy need to stick it out and finish anything I start. This is the first book in decades I gave up on. That should sum it up.
