I just got home from seeing The Hunger Games and loved almost every minute of it. There is some violence, but they do not dwell upon it for long and there is plenty of compassion shown to counteract it.
Having read all three books, I was not ready for the movie to end when it did - even though it is 2 hours and 30 minutes long and I had been sitting there for 30 minutes before it started. I hope that the powers that be decide to film the other two books; I will be in line to see them as soon as possible!
Even though the books were for young adults, I read them with relish and couldn't wait to find out what happened in the story. I hope you will enjoy them too.
Edit: don't let it phase you that the books and movie are for young adults. It only means there is no profanity and no sex.
