I watched the movie last night, and it was good, but in a strange way.
Having 12-18-year-old kids fight to the death in an arena where the adults at the controls hurl deadly obstacles at them is downright demonic, even Satanic, in my opinion. I'm not familiar with the series as a whole right now, since I haven't read the books, but I hope that those demons at the controls one day get what they deserve in one of the later installments. It's certainly an interesting concept, I must say, but it's morally very wrong. I would deduce that in the final book, which is being split into two films (like Harry Potter and The Twilight Saga), the Hunger Games that are held in that book would be the final Hunger games, and I'm sure that Katniss would agree with me that such an event should never be held again, ever.
Also, for some odd reason, when I watched the movie, I couldn't help but think of Mortal Kombat, as I could imagine Shao Kahn being the announcer of the games, and saying the word "Fatality" whenever one of the kombatants is killed. Mortal Kombat, indeed.
