I remember some one mentioning to me that the Avatar movie made no lasting impact on popular culture, which I sadly have to agree.
Avatar is kinda there in the background, gone but not forgotten.
I know several folks in RL who didn't watch it in theaters who've watched it since and kinda wish they'd had the big screen 3D experience. I guess at least half would probably go see it if it was re released in the run up to Avatar2. And, while a few fans have sadly passed now, most of those who saw it back in the day, would likely go see it again if they could - including me.
Plus, don't forget Walt Disney World Resort’s big new attraction for 2017 is Pandora, The World of Avatar
The teasers look pretty amazing.
