James R. Rogers on debt, gift, and sacrifice in the Hunger Games :

The book, The Hunger Games , is of course better than the movie. The book’s story moves with the internal dialogue of the teen protagonist, Katniss. In contrast, the film’s story moves along through events external to Katniss. As a result of this shift, the film throws away our window into Katniss’s mind and, significantly, into her moral psychology, both of which are by far the most engaging part of the book (and the entire trilogy of books for that matter).
