The people of Gary, Indiana have been left in the dark long enough. Mayor Melton and neighboring officials are pointing directly at NIPSCO for failing to maintain their infrastructure, and now 10,000 families are still paying the price. This is unacceptable. These families are waiting on an executive order to declare a natural disaster while their food spoils and their lights stay off.
I hope @JamesGunn includes a fight scene with Superman and Supergirl against some villains, where Superman holds back. Afterward, Supergirl questions why Superman is being so restrained. Perfect opportunity to show that Superman has a mental block on his powers.
