Alright, setting the recent political wank aside (I don't EVEN have an opinion*).
So here we have Walt Disney World teaming up with James Cameron, a filmmaker who goes big, shoots for the moon, wants to blow the audience's mind, wants to show people things they've never seen before, has created some of the best-selling films of all time, and who, above all, basically invents technology along the way just to get a movie made.
Just like this filmmaker did:
Try to argue it.
So I have no problem whatsoever with a Disney/Cameron Marvel Teamup.
Now as far as the film "Avatar". Guys, very few people were enamored of the story, even the hardcore fans. Why did people keep coming back to the theater? Why were an alarming number of ordinary folks crying at night, wishing they could turn into Navi and live on Pandora**? I'll tell you why:
World. Building.
Pandora was built in excruciating detail from the ground up. Some of the most creative minds were put in charge of every detail. I was sold on the movie once I heard Wayne D. Barlowe and Neville Page were involved. (As you may have guessed, I am a creature design nutcase.) So this is indeed a world as detailed as, say, Hogwarts. (I'll give you Star Wars, since we're dealing with several planet's worth of Barlowe and Terryl Witlatch critters rather than one planet we haven't even seen the aquatic fauna of -- yet.)
So there are a lot of interesting opportunities to be had here. One possibility I like (aside from the fairly obvious "Trudy Lives!" flight simulator, "Soarin' on a Turok", and "Neytiri and her Forest Friends"

) is an exhibit of the real organisms who inspired the fictional creatures: Lemurs, Ocelots, Tube Worms, Birds of Paradise, Lanternfish, Butterfly Lizards, Tree Ferns, Raffelasia, Flower Hat Jellyfish, and a whole slew of plants and animals who are strange, awesome, and need more love.
I've got the same attitude I already had with the Fantasyland expansion: I'm trusting Disney can pull it off and am ready to enjoy something new.
Because in the end, we are getting a new themed land out of this. Y'all HAVE to agree that's worth getting excited over.
(Now what are the chances anyone's going to notice my one post in the deluge?)

* - Now that I alluded to it, does Disney still own the rights to the Miramax films made when they were part of Disney? Hell, we could have Tarantinoland!
(Seriously though, a defictionalized Jack Rabbit Slims in DHS would be neato if at all possible.)
** - To which I say, my God, pull yourself together and book an ecotour of Costa Rica. Earth is pretty too. And real.
