• James Cameron's "Avatar: Fire & Ash" surpassed $1 billion at the global box office.
• Cameron now has four films in the billion-dollar club, more than any other director.
• So why is he not considered one of the greatest living directors?

In an era where it's nearly impossible to get people to pause their daily lives, put down their devices, and visit a movie theater, James Cameron has defied the odds and given the movie business hope that not all is lost.
