It was the worst thing in the world. LOL getting around the morality of marriage by committing an atrocious satanic travesty (SATANISM). You really need to examine your thoughts if you think OMD in any way was good or its payoff.
And what the hell does Supes being married have to do with Spidey. Spidey was married first than Supes and was thoroughly interesting. The times Marvel moved against the marriage they were met with fan backlash. They couldn't take a hint that the readership didn't want the marriage dissolved.
All those stories where Peter joining the F4 or Superior Spider Man could've been done with a married Spidey seamlessly. Spider Man's marital status does not make him boring in the least but rather the shortcomings of the writer.
Dan Slott controls the current direction of Spider Man but he cannot dictate what future writers will do. Wise words from Tom DeFalco.
