I saw the first Hunger Games movie before I ever read the books, but I enjoyed the movie enough to buy the Kindle book version. This is a well written trilogy, and you experience this world from the first person perspective of the Katniss Everdeen character.
Both the Hunger Games and Catching Fire are very well written with a tight narrative, but the storytelling gets a bit too expansive and jumbled by The Mockingjay. I would say the 4 movies are the most faithful and accurate adaptations of novels I have ever watched. There were very few deviations from plot, theme, and character. The only notable of those would be the elimination of Madge Undersee and Delly Cartwright and the increased presence of Effie Trinkett in the Mockingjay. I found Mockingjay Part 1 and Part 2 better than the book, actually.
Overall, I find the premise and setup of the story quite interesting, if not a little bit too plugged into the Climate Change hysteria. It becomes obvious from the books that the real issue creating slavery and hunger in this dystopian world is government control and overreach, not rising sea levels. There appears to be abundant food out beyond the walls of these districts, if only the people had the courage or opportunity to venture out there.
In summary, a fast read for readers of any age and an excellent addition to the debate and discussion of government power, oppression, and other relevant topics.
