I chose Hunger Games as my Government Class book last semester. I liked it so much I read the second (Catching Fire) and third (Mockingjay) and then ended up presenting on the third one. Personally, I think the first is the best, the second one is still great, but the third was kind of a let down but still essential to read if you read the first two.
Anyway, now to your question. I think definitely that the media has an effect on us. There is no such thing as being completely unbiased, so whatever view we see from the media is biased in some way and affects our thinking. If a government completely controls the media (Like in Hunger Games), the government can essentially control how people view events.
Also, I'm looking forward to the movie!
