I don't get why people feel that Avatar belongs in Hollywood Studios - yes it's a movie, but is that really the only tie in? Admittedly it's not a natural fit for any Disney park (it would have been the same deal with Harry Potter), but I think in this case Animal Kingdom is a better fit. Stressing the beautiful landscapes, mythical animals and the nature aspect of Avatar makes the Animal Kingdom a logic connection.
If Avatar didn't exist and Disney came out last Tuesday and said that they would be opening a new land in the Animal Kingdom called Pandora that would bring guests to a far off land full of mythical creatures all the while connecting them with the environment around them, we would be excited. But because there is a commercial tie in there is opposition. I don't get it. We don't know the particulars, we just know that Disney acquired the theme park rights to Avatar and Animal Kingdom is getting an expansion based off that franchise.
I liken this to the people that are detractors of The Wizarding World of Harry Potter despite never having been there just because they weren't a fan of the books or movies. Your appreciation of the source material does not correlate with the quality of an attraction or area. I've never been to Africa, does that mean I can't appreciate Harambe? I'm not a Star Wars fan, does that mean I can't appreciate Star Tours? Song of the South denegrates African Americans, does that mean we can't enjoy an attraction that focuses on other parts of the movie?
If you don't like Avatar, that's fine. I was indifferent towards it myself, but I will certainly be watching it again prior to this land re-opening. Even it's detractors will have to agree that the land of Pandora lends itself to an incredible environment. If that can be replicated I fail to see how anyone could justifiably complain that they dislike it because it wasn't originally created by Imagineering but instead, James Cameron.
Here's where I'm nervous - We don't know the attraction lineup. I don't doubt the land will look spectacular but the wild card will be the quality of the attractions themselves. When more information comes out, then we can have a discussion about the pros and cons of what they've proposed. Right now though, we can only deal with what we know - Pandora is coming to the Animal Kingdom.
