I think there's too much game playing with the cloud and companies' ideas of what it means when you "buy" an ebook or DVD video file. Hint: it doesn't really mean buy. A DVD might not last forever, but it's less ethereal than the alternative. So people still buy them.
I actually liked the Hunger Games movie quite a bit. I had never read the book, but I really liked how the movie's writer and director took the presumed "young adult" (teenage in publishing speak) very seriously. They didn't treat them like idiots as is often the case.
