Hunger Games is sci-fi. But compared to other sci-fi novels it is a watered down "kiddie-ride" of science fiction. It only brushes by traditional sci-fi pretenses like survival, utopian/dystopian theories, and authoritarian control vs. individualism. But the book DOES act as a primer for this amazing genre of books, and, with a strong, young female in the main role it can only do more to bring down social barriers.
Actual quote: “Interviewer: So why do you write these strong female characters?
Joss Whedon: Because you’re still asking me that question.”
But commenting on the importance of the success of works like this, is off topic. Sorry.
Being the shallow side of the sci-fi pool in novel form, I was not surprised at all with the treatment of the movie. Hollywood has so much trouble adapting sci-fi in a way that truly captures the feeling and message of the source because they want it to be popular to a majority, while HG, the novel, itself tried to send traditional sci-fi ideas in such a rudimentary way because it wanted to appeal to a mass majority
It was destined to be lacking.
