I really don't like that version of the Spectre at all. I like the original Spectre a bit better, but I acknowledge it has the same issues. I'd say lots of gods from lots of religions/mythologies are the "real" one in comics. Doesn't make any of the belief systems correct, though. And I understand Marvel went the alien angle with Thor (never read that one), which I don't like for diminishing that one and not the Abrahamic one the same way (unless they did that, too, I guess). The worst though was an old one where Wonder Woman referenced a one God above all others thing in what seemed a clear nod to the Abrahamic God. She just shouldn't think that way.I'm kind of divided about the Phantom Stranger (and the Specter also). On the one hand, he's a very cool and mysterious character, larger than even our heroes are.
On the other hand, it solidifies the idea that Abrahamic God is the real one and I really don't like it for plenty of reasons.
And I'm not really that keen on what happened with Doctor Fate, either. Guess I don't like a lot of concepts that went over well.
