Lois has had important roles in both Action and the first arc of Superman, plus she'll be an important player in the First Superman story in Action. She's hardly been forgotten.
Well, DC didn't really break up the marriage. It seems to me that they went back to the beginning of the story. I'm in favor of the marriage and enjoyed it. To me, it felt like a natural progression of the story. I do find it strange that so many people try to lock Superman down into a specific, similified viewpoint. Superman is a complex character. He should grow and change as his stories progress. I think that all the aspects of Superman that people tend to argue over should all be incorporated into his myth. It's just my opinion, but I'd like to see Lois and Clark together again as a married couple. It just makes sense to me. Even with the Kents dead early in Superman's life, they provided a loving and stable home for him. People tend to seek out what they grew up with. If he had great parents like the Kents, it seemed natural to me that he would want a family someday. Though really, that's someday. It doesn't have to be right now. As a young man growing into godly powers, he'd have to find his place in the world first. I can see where a peson with amazing abilities like Superman's would need some time to figure things out. Plus, Superman knows his world is dead a gone. He has to piece together his own roots and learn who he is.
So really, the single and isolated Superman and the married family man should all be part of the same story, in my opinion. As a young man with powers, I could see him seeing out romance with other women who have powers, as it would seem like common ground. Then he learns what he wants in a partner and discovers it's been there all along. It's a classic tale. So why not tell it to us and let us enjoy the ride? Take us through the life of the greatest superhero ever and show us why he's so great. I think we'll all find that there is something in there for all of us.
Over in Action, in the early years, both Lois and Clark are kind of hot headed, no nonsense, go getters. Over in Superman, they are both successful career people who have mellowed a bit. They are more comfortable in their own skins, so to speak, in Superman. Now that Superman is powered up and a public figure, he's dealing with his role in the grand scheme of things. So is Lois, with her role as head of a multimedia news organization. They are actually progressing at the same rate, as far as character growth. It actually seems that they care for each other and are kind of "growing up" together. Clark is kind of hurt by the idea that Lois may have a boyfriend in issue 1 of Superman. When Lois gets her big promotion, the only one she wants to celebrate with is Clark. Lois looks out for Clark and Superman, always behind the scenes protecting him. So it seems to me that they do have feelings for each other. Right now,m they have a lot of other things to deal with. It wouldn't surprise me if they end up together again. Then we have the adventures of the single Superman heading towards the married Superman. Seems to me, everyone stands to win something here.
Why does it have to be exclusively one or the other? The story should progress. No one gets to have "their Superman" all the time. It's not fair to ask for it either. Different people obviously like different things. It's not some exclusive club here. New readers have every right to get in on the ground floor and experience Superman from the start. Long time readers have every right to have the story progress to the elements they enjoy. It's a story. You really can have it both ways. I think the problem is that comics in general tend to be frozen in time. Because the story is expected to continue forever, nothing can really change. If it does, you have reset the whole thing and start again, so that nothing really has changed. It's not a problem specific to Superman. So when change comes to a comic, it's shocking to the readers who have to expect a status quo based on where they started.
Yeah it wasn't really about undoing the marriage so much that they wanted to rewind the clock and tell stories about a young, fresh Superman. That's all there is to it.
I say, if DCNU truly cares about Lois Lane, even despite forced retro-retconning the marriage out, do something good for her to use her in; another solo series of Lois Lane, or atleast an ongoing for the Lois Lane-headed Lois Lane and the Resistance please.
Based on what JMS said of this storyline, it's not that Clark won't ever be with Lois in "Earth One". Rather, he's showing how Clark will have to learn how to deal with relationships with his own powers. But there's nothing against Lois in general. DC is doing this for their own reasons and regardless of what we think on the subject, they're going to do what they feel is best for business.
