I don't read much science fiction, fantasy, or dystopian literature (not sure where among those genres The Hunger Games technically falls), but I thought the premise of the series was intriguing. At the same time, I was disturbed by the notion that Collins wrote this series for children (teenagers are, after all, still children). I was creeped out by the idea of presenting kids with the specter of a society in which children are nothing but pawns for evil adults (okay, despite my sometime-cynicism, I'm essentially naive and over-protective). And the level of violence, the horrible ways in which people are killed, and the number of killings done by children made me cringe.
Of course, I thought Lord of the Flies was one of the best books I had ever read when I encountered it as a teenager, and it was about kids doing unspeakable things. But Lord of the Flies didn't, in my opinion, use violence as entertainment, which I feel The Hunger Games does. And make no mistake, the books are entertaining. I just hope my grandchildren don't read them until they are 20 or so!
