Not to mention that 2 out of the 3 main iconic locations in the first film were destroyed by the humans. We still have floating mountains, but Hometree is blown up and falls at the end of the film during the battle (fine, DAK already has a giant tree in it) but the other -what could have been a beautiful, and reasonably sized centerpiece to part of the new land- the Eywa Tree of Souls, was bulldozed by the humans halfway through the film.World building in literature seems to be a bit more of a recent construct. Fantasy has been around a very long time but the concept of creating a working world within a story is something that's become more widespread in modern literature. With a wide reaching world crafted, a themed land can be created because you have the sheer volume of material to work with. It's interesting to consider the fact that without the detail in the books, the lands couldn't feel nearly as rich for HP. Avatar is a beautiful visual experience - but it's screen time wasn't dedicated to the little things we hope to try in a theme park representation. The Banshees are the largest "I have to try that!" experience I can think of and that's one ride...
I would've loved to see this in the land:
Who knows, maybe they will still have it. And as you walk around the tree you hear whispers from the souls of the dead, using audio projection technology, so it feels like it's right in your ear.
I'm hoping for a little more lore in my Avatar Land!
