I think big budget CGI films are what is wrong with the film industry. There is a "forget the story, this looks awesome" mentality and most people buy into it. (I'm looking right at you Transformers.) Disney has even admitted that with tent pole films the plot doesn't really matter.
Having said this, let's talk about Avatar land in Animal Kingdom. This seems to be Disney's solution to Harry Potter World at Universal. Harry Potter is a time tested franchise, it's a world wide phenomenon. Avatar is the biggest block buster of all time, I credit this to the film being released in 3D and Imax, where your ticket price is going to be $30 a person. The general consensus I hear about Avatar is "The story was kind of dumb, but the special effects are awesome." This is a terrible way to describe a film.
I don't think Disney needs to rely on third party franchises to base their attractions/lands on. It worked well with Star Wars, but that is also a time tested franchise that people cannot get enough of. (Even when George Lucas keeps screwing them up) Does Avatar really have the following of Harry Potter and Star Wars, or was it so hyped up that people went to see it?
Back to Avatar land. If they build it at Animal Kingdom I won't really care. The closest I ever get to that park is eating at Boma. So keep your movie themed land in your worst park, I'll meet you at Epcot. Still, is this something that 6 years from now will have to be remodeled and renamed because no one cares? (This time I'm looking at you American Idol Experience!)
