Honestly, I have my doubts about that.
I mean, even if they all work together to stop Steppenwolf, there changing the Superman Resurrection Fight Scene to something that doesn't make the league look bad is only going to go so far in not making it as if he overshadows them entirely.
But, again, I could be wrong on that. My point was, Superman showing up and saving the day is just one aspect of that sort of portrayal, and it's going to be hard to minimize it no matter what they do.
That, and after seeing that clip of Wonder Woman vaporizing a guy and then turning to a girl who wants to grow up and be like her, which she encourages...
I'm just... it looked like the parody origin of a supervillain.
Throw in some philosophical distinctions, tiredness of the desperation to be 'taken seriously' in an inherently silly subgenre as a tone ("Adolescent Storytelling" to draw on C.S. Lewis), and I just can't muster up the interest.
