Regarding the movie, I thought it stayed pretty true to the book, although the Gale and Peeta inside my head were not like the actors in the movie. That said, I thought all of the actors did a really fine job bringing the characters to life. Katniss, in particular, was pretty close to perfect. Oh, how I love strong and imperfect heroines (and heroes)!
The best part of the movie for me was when the story moved into the actual Hunger Games. Pretty intense. Great visual effects, like with the genetically-engineered bees/wasps thingys. I don't recall the weird, carnival-like feel of The Capitol in the book, with all of the citizens in Willy Wonka and The Chocolate Factory-like costumes and get-ups, but it's been a while since I've read the book too. Even so, the contrast of the elite-like people living in blissful ignorance in The Capitol versus the poor schmucks surviving in the Districts with no rights and living on meager government handouts was perfect.
Missing from the movie? Music. The movie lacked Big Music--the kind that gets your blood pumping and your heart welling with unbridled emotion. It needed something larger than life. It definitely needed more music.
All in all, I'm looking forward to the next movie installment!
