Hunger games. Book was better but movie wasn't bad. The movie didn't capture the desperation of the districts nor the brutal sadism and soul crushing tactics of the state - but this was more evident in the latter books. So hopefully this comes out in the sequels. The author's interest is exploring how war affects adolescents, which the book did an excellent job at - near to Orwell's 1984 standards IMO. Hope the rest of the series is more serious.
