Alas, most of people saw Avatar, and believe that it was the best movie in the history of genre..
If you haven't seen it, find the incredible review of the Phantom Menace on YouTube by Red Letter Media. The most insightful part is where he asks people to describe the nature of the characters in both trilogies. For the original movies, people instantly recall, for example the "dashing...arrogant..scoundrel" Han Solo. For the newer films, nothing. What was princess Amidala like? Nobody cares.
Avatar suffered from this, and no amount of shiny graphics could ever bring me to care. With great characters you can forgive all kinds of things (eg Battlestar Galactica.)
Stories like these are part of what makes us human.
