8. God's Among Men
This is more a thematic necessity that I think helps facilitate keeping the team together and in order. There's going to have to come a point in the film where mankind is going to have to back up and say, "Who are you, why are you here, and why are you making things worse? You're not saving earth, your aiding in its destruction by being so powerful." I know a lot of folks hate that attitude, but the Justice League needs a solid thematic point to clearly set itself apart from being an Avengers copycat. That comes from the heart of the story and the heart of these characters. Mankind needs to turn their back on the Justice League as fearing what is essentially a team of Super Gods. But when the chips are down and mankind is essentially held captive, the League needs to show them that despite mankind giving up on them, they'll never give up on mankind. They're the Justice League, they fight for good despite whether or not people "believe" in them. This will give audiences reason to sympathize with and really care for the team as a whole. This is an entire group of people who refuse to give up the fight to save the world, even when the world has turned its back on them and all hope seems lost, these seven have a marine mentality. They are the first in and the last out. We need a reason to connect with the League on a level above the Avengers. What the Avengers didn't touch on or deal with is what these heroes mean to mankind. Yeah we got our cute little montage at the end where Stan Lee plays chess in the park or whatever, but we need the League's relation to people to be an important dynamic throughout the film. These are God's among men. Regardless of whether or not they're good or bad, how would we deal with the knowledge that they're here and they're here to stay.
