From other reviews I've listened to, it seems to be a very reader-targeted movie. I haven't seen the movie (yet,) and I'm personally starting the 3rd book, and although the plot does seem interesting and has some original satirical themes, it doesn't seem to thrill me as much as most people. This is most likely due to the fact that although Katniss is a strong protagonist in the trilogy, she's always spiteful, cynical, and moody, or at least she is to me. And yeah, I would be too if I was a starving child that had to hunt all my food and constantly break the law of a tyrannical government regime just to survive, and while contending in the hunger games got to witness the indulgence of the "1%" in the Capitol. But the point still stands, for me, she's hard to like sometimes.
As far as the plot not moving anywhere in the first movie/book, they both seem to suffer from "First installment syndrome," in which the first installment of any sci-fi or fantasy series or franchise has to consist mostly of, if not all of, setting up the mythos, tone, setting, etc. It needs time to sink in as the "norm" of whatever universe the series is for, before the next installment in which plot elements start to move in more quickly and heavily. Sometimes it's a necessary evil so the plot elements can actually feel like they matter, but you can still feel it going on in that first installment that just explains how everything works, especially in young adult series' such as the Hunger Games, which can have slower pacing, lighter plots, etc. As opposed to adult-targeted series.
