While I appreciate the universe being interconnected, with Brainiac being tied to the origins of Kal and Kara, I do like seeing the possible dark future of our own Earth reflected in Krypton

I like how SyFy's Krypton did both with Brainiac being the main threat to cause Krypton's core to be exposed, but also it was indeed years of neglect by the council that leads to it still.
