The first book was the best of the trilogy, IMHO [Mockingjay being the worst, again, IMHO].
Personally, if they stay as faithful to the source material as possible, then the movie adaptation should be more than satisfying. The thing about it is that half the cast in this movie will be gone by the sequel, and in 'YA' book-to-movie adaptations, that's never been done before IIRC [well, the Narnia movies, maybe, if you count that as YA, which I don't].
PS
Hopefully, this doesn't degenerate into the "Team Gale/Peeta" BS. Which looks likely. Damn fangirls...
