Do you remember Avatar? It was released seven years ago as the single biggest movie of 2009. But unlike other sci-fi blockbusters with broad family appeal, you'd be hard pressed to find anyone today begging for a sequel, let alone clamouring for theme park rides based on the film. But that's just what we're going to get next winter at Walt Disney World. The company announced that Avatar Land will open at Disney's Animal Kingdom park during the winter of 2017. And the fact that it's opening long after anyone cares about Avatar shows precisely why it's so hard to keep Disney's Epcot theme park "futuristic".
