Can you think of many books that get a ton of attention they actually deserve? I really think in most cases, it's good marketing or notoriety rather than actual book quality.
I have never heard of that one -- must be out of the hype loop for it! ETA: I just realized you said it was being made into a movie, which helps explain my cluelessness. I am definitely out of the movie loop.
I agree that most books that are hyped-up really don't deserve it. I've been tricked into so many books that I had been assured were amazing, only to be disappointed.
The Hunger Games might qualify. No one, at least that I've heard, has tried to say it has amazing writing, just that it's a good story and a good read. Oh, and Harry Potter! Totally worth the hype IMO.
