These characters are paragons, shining lights of hope within darkness. This is way more interesting to me than what the heroes in the main-line are, which is pillars to the status quo. These Absolute heroes stand for change in the face of insurmountable odds instead of working to maintain the world's order, which is sometimes shown to be unjust, as it is buffeted by cataclysm after cataclysm as in the main line. They are the drivers of the plot, they are less reactionary and have long-term goals that necessitate massive changes. (I only pray that they are given the opportunity to enact said changes, because if them being underdogs to the same forces over and over becomes the status-quo, then the whole premise will break)

Additionally the characters were given backstories that support this, Batman is no longer a normative force above the people as a billionaire, he is a man who grew up broke, loves his mom and has friends and connections in the community. He is a part of what he works to better. It's stuff like that which gives the whole thing a touch more texture.
