Yeah, I don't know. There's an entire section of Disney World devoted to this and there are some sequels coming out. It's not as big as it was, but I think this one is still bouncing around.
I think Disney and James Cameron have severely overestimated the appeal of Avatar. I think it worked the first time because the effects were great and it created an entire new world. But that newness has worn off long ago and it's effect aren't that special given today's tech. I mean, I went to Avatar world at Disney. It's a cool looking place and there is one great VR ride, but I wasn't in any way drawn by the fact that it was Avatar. It was just finally something new to do at Disney.
