It's a fact that in the past several years DC has almost caught up with Marvel in comics sales. Take away Star Wars, and DC is well ahead now. I've posted the graphs several times about DC's and Marvel's sales that date back many years. I don't care to do it again.
And it's a fact that television has found marriages tend to hamper writers. Not just the "uncreative hacks." Marriages tend to work better in sitcoms than in dramas. But even in sitcoms, many characters are unmarried.
