What do you think will be Crisis on Infinite Earth's legacy today?
My opinion, in the grand scheme, while I still have fond memories of the story, it's one main earth idea is pretty much undone. The Multiverse has been back since 52. We are far from having only one Superman on the main earth, let alone the Multiverse. It seems we are in a more cluttered continuity than even early 80s DC was at the time.
