The Avatar story does seem too self contained for a very good play pattern.

Most of the really important stuff happened during the movie and then the bad old humans got sent away so it was all happily ever after.

Transformers always seemed like there was a bigger universe but we were only getting part of it. Even kids could see how the GI Joe movie was setting up for Cobra Commander and Destro to escape. Always some new super villain out to stop the super heroes. Star Wars always had that feeling of some many worlds out there where so much could be happening with the Empire and Rebels.

Just feels like the events in the Avatar movie are it though for Pandora. No more bad guys to deal with just the Na'vi going about their every day lives.
