Books adapted as movies can be a mixed bag. Some breathe new life into an already wonderful story. Many many many disappoint fans of the book, especially in recent MG/YA adaptations. I'd name names, but that might hurt might chances of getting movie deals with the production houses that put those duds out.
Actually, that might not be a bad thing--sort of a self-selection for awesomeness.
So, when I first heard
The Hunger Games
was becoming a movie, I started seeing scenes in my head. Now
the first trailer has come out, and the energy of it seems like a wonderfully faithful to the book... except that Katniss wouldn't make all that NOISE walking through the forest! Hello? Foley people? Take it down a few notches! How would she ever frikkin' HUNT? That's the amount of noise an
actor might make walking through nature, not someone who has to
hunt to live--someone who's been doing it for years!
*sigh*
