I think it did a pretty good job of keeping with the book. I wish more of the cave time between Peeta and Katniss were in the movie. I also think the bread/pig scene should have been shot with younger actors since they were younger when that happened.
I think it was important to show more of what she was losing by picking Edward. I was very disappointed not to see the vision of how her life would have been with him. The two black haired kids they would not have together. Or how about how he can't fight an eclipse!! Or how much she cried over losing him. I'm just sayin'
