The production values are high, which includes James Newton Howard's sweeping score. We get plenty of visual effects work from Rising Sun - I did like her flaming dress and all those high-tech computer interfaces. There were digital cities creatures and crowds that all went to flesh out this twisted little place that was close enough to our own world to really hit home.
I liked the realisation of the extravagances of the capital in contrast to districts and their poverty. Combine that with the struggle for these kids to stay true to themselves in the context of a life and death struggle and we have a quite adult film that appeals to quite broad spectrum of ages. We are left wanting more even which is a good sign of the quality on display here.
