Even with depressed U.S. grosses because of massive snowstorms in New York, Philadelphia, and Washington DC, Avatar finished Saturday only 5% down from Friday. It's the best-ever debut for director James Cameron, best-ever opening for a 3D movie with IMAX shattering their records and selling out every seat and adding shows to keep up with demand.

James Cameron has delivered everything an artist can possibly deliver in a popular genre. The story may seem familiar, but that is because it is timeless. There are only so many great themes. To say it's been done before misses the point, when it's done this well.
