Yes, but here's what you're missing.
A GOOD marriage makes you a better man. Because with a solid, stable relationship, you don't have to keep all the crap inside that you normally do. Any capable writer could have taken the marriage in a hundred million great ways, but they had no clue how to, other than to add damsel in distress or shlocky soap opera crap to their stories.
Perfect example of bad and good writing with a marriage and/or kids:
The last Flash run was horrid with it. They jammed the marriage and those kids down the reader's throats SO BAD that I couldn't even bring myself to care about either.
The last issue of JLA, Flash mentions his wife and kids TWICE. We don't see them at all. And it worked for me, because they were on his mind, but not the focus of the story for once.
MJ didn't HAVE to show up in every book. Just enough to establish the marriage as solid. A little levity would have been nice, too. Not the WOE IS ME non-stop crap.
