I think it made so much money at the box office because it was so visually stunning (for the time) and no one had made a movie like that at that point. It was very much a movie everyone said to go watch on the big screen in 3D, ideally IMAX 3D. I never did and only watched it on a DVD borrowed from my wife’s friend 6 or 7 years ago, and came away less impressed. Like, it’s fine, but the movie itself isn’t exactly the greatest story ever told, and the visuals, while groundbreaking at the time, are now pretty standard.
