Superman works because he's not invincible.

He's a "man" who overcomes what nobody else can, but sometimes even he isn't enough.

His greatest weakness is being an alien "god" with true humanity. Should he sacrifice the Kents to save the world?

Could he?

That is the definition of why the Justice League exists.

It's also the way other characters are defined.

Dredd is raised to be a "perfect" Judge, no family, no ties to alter his actions. But it's a lie. Rico isn't executed despite his crimes. Dredd ignores how his informer, Max Normal hustles and edges around the law. There's his "fwend" Walter the Robot...

Batman's faults need no introduction, because infallible characters have no place in DC.

There are just 2 trailers, but it looks right, it feels right and that new version of the music reminds me of how it feels to believe a man can fly.

I see it as a reboot of Christopher Reeve.

Man AND Superman, an idealist in a far from ideal world. His humanity is from the Kents, his powers are alien, even to himself.

If JG gets the balance right , it's the right move.

If it's good, it will stand next to the Donner original as THE Superman.
