Avatar is a really odd piece of entertainment. By most calculations it’s the biggest movie ever made (thanks partially to a lot of 3D showings), but it didn’t engrain itself into pop culture whatsoever. Besides Jake Sully (because they say his name a jillion times), I don’t remember a single character or memorable line from that movie.
But I think everyone can agree on two things: it was really pretty, and those flying dinosaur things were cool. So while I doubt many people are itching to see an Avatar Land, I think a really, really pretty chunk of Pandora that people can walk around in – with a ride where you fly on the back of those dinosaur things – will translate well to Animal Kingdom. Especially now that it’ll be open at night, so things will be all glowy and neat looking.
