>>108159964The point being made is that audiences did not require 2 hours of "Superman was a baby on a doomed planet, sent to Earth and raised by kindly farmers....ect." There was no need to create a retelling of anyone's origin for a Justice League movie.
Cast good actors.
Write some solid dialogue that defines their personality.
Play them off one another, and put them in challenging situations they solve in their own unique style.
Audiences are now Entertained.
Of all the original Avengers, only the Hulk could have gotten away without some sort of origin, but got one where they changed it away from a bomb test gone awry.
You can't just have Captain America show up in that Avengers costume and not explain wtf is up.
