First, let me say that I LOVED the book. Second, let me say that I attended the movie knowing that I always prefer the books to the movie versions. That being said, while this was an enjoyable movie, I was VERY DISAPPOINTED with the lack of character and relationship development. I also think they really missed the boat by not being more clear that the citizens of the districts are STARVING (thus the name "Hunger Games").
On the other hand.... LOVED how they depicted the Capitol, LOVED the firey outfits, and LOVED watching the GameMaster in action. I also thought casting for Katniss was well done.
All in all I enjoyed the movie, but left a bit disappointed.
