Big Question about DK

I recently reread Dark Knight returns and read dark knight strikes again (vastly underated and needlessly panned). and i was just wondering, are miller's books set in the future of the Silver Age?

I have no idea. 😕

Yes.

And tho it wasnt as shitty as some people make out, DK2 was a huge disappointment compared to DK1.

how so? it's supposedly the middle part, I hear rumor of a DK3
