Well, to me, its pretty lame. Crisis made all these points about creation, Chronos, the Guardians, whoever those dudes who made the Manhunters were , etc. (sorry, my memory is failing and I hate all that Bronze Age mumbo jumbo
) and at the same time DC forgot their own 80s mythology in that the Spectre stopped Supes flying too fast and said "hey man, my master (GOD!!!!) doesn't dig it when you fly too fast because you are in danger of breaking the celestial barrier".
And the Spectre alone couldn't have lectured the Anti-Monitor?
