This should be the plot for Man of Steel 2
It has been confirmed that Batman v Superman is not a Man of Steel sequel, and they will do a direct Superman sequel.
Now that Wonder Woman and Batman are being introduced in the DCCU, this plot is perfect.
The only thing messing with it is Melissa Benoist already being in a Supergirl show, but they can just cast someone else or ask her to do it.
Imagine: The Furies of Apokolips are played by actresses who were considered for Wonder Woman. I'm talking: Gina Carano, Megan Gale, Jamie Alexander (probably not), Gemma Arterton, and Bridget Regan or any other awesome actresses
I think it would be an epic film. Only thing I can think of holding it back is the Doomsday clones, but that can be changed to Parademons
