#AvengersEndgame has not just been a success at the box office - it has also drawn widespread critical acclaim. Reviews when it was released spawned descriptions such as "glorious", "irresistible", "intensely satisfying" and "masterful". But, #Avatar officially passes Avengers: Endgame at the worldwide box office to reclaim its title of the highest-grossing movie of all-time. James Cameron's original blockbuster pushed 3D technology forward in 2009 and became a global phenomenon in the process.
