A lot of people considered Superman's journey in Justice League to be the highlight of the film. Here is a more idealistic, hopeful Superman, in bright colours and grinning heroism. This is a Superman we can believe in.
Fan and film editor Jon Arryn Garza seems to agree, and his edit "The Return of Superman" focuses on turning that renewal into a more fleshed out character arc.

Here, finally, Superman makes his choice. And he chooses to help. Watch it below.
