The first book has basically no political commentary.
Although the government of Panem is presented as evil, there are essentially no evil or unsympathetic characters in the book. Even the people who are government tools are presented favorably just because of their support for the main character (despite collaborating with the government in conducting the games).
If you wanted to read a political commentary into the book it'd probably have to be something extremely cynical like, "Teen girls don't care that their private fashion designers just sent them off to be killed, as long as they looked beautiful!"
The world building in the book is incredibly weak. It's said at one point that the population of District 12 is around 8000 people. If we assume it's not unusually large or small (it's never mentioned that it's exceptional in that respect), then the whole nation of Panem is looking at around 100,000 people. What happened to all the people? What happened to all the ruins of North America that surely would be left behind? Why is coal an important industry (and how can a miniscule town supply enough for all these people) when Panem has technology far in advance of our modern day?
Thanks for the heads-up on the book....... I probably won't be reading it.
