Forget the thoughts of Superman ever marrying Lois, forget the thoughts of a super romance, because Superman can't make love to a mere mortal without hurting or killing her. Forget about the marriage in the comics, and, not least, forget about LNC:TNAOS.
Why? Even if the movies go that route, which would suck, it wouldn't undo what's taken place in the comics and it would certainly not undo the four seasons of LNC. Those are still going to be around for people to enjoy.
