I'd call it a good adaptation that dances on the edge of being great.
I liked the new stuff, and I can see why they did it. It foreshadows the events of the latter movies more, and gives more of the Capitol's POV. The discussion of why they have a winner, in particular, I thought was a good scene.
Jennifer Lawrence was great, as expected. Actually, as the opening shots appeared it occurred to me just how similar Katniss' basic setup is to Ree in Winter's Bone (teenaged white trash girl who hunts and is responsible for caring for younger sibling(s) becauser her father is dead and her mother is non-functional. She's really an amazing actress.
I think Rue really needed another scene or two, but the actress playing her was very affecting and natural.
Also, and this something that's true of both the book and the movie, since we're told that this is a show constantly, I do wonder about the "career tributes". They're basically the villains of an 80s teen movie; in wrestling terms, they're the "heels" of the proceedings, and yet we're told they almost always win. That doesn't really seem that audience-friendly.
