I think that story you're talking about actualy from a what if. Marvel Graphic Novel #38 has Silver Surfer agreeing to sell his soul to Mephisto and that didn't happen, Mephisto was having a good time torturing Silver Surfer.
Younger heroes could also start to respect him by him just listening to them and giving advice, 'cause once in a while I get this impression Spidey iHmm, yeah, Peter's inability to keep a schedule (because of his heroic responsibilities) is a flaw that many of us in real life do have to struggle with, and I definitely agree that he shouldn't be treated like an idiot by other heroes, especially the ones who've been around long enough to see his brains in action. I can forgive the younger generation of heroes for not having been around that long to witness Spider-Man's amazing brainpower, but even then, it would be cool if he just got to have more of those moments where he shows them what he can really do and they're just as amazed as we the fans.
You mean the 80's, since the MGN#38 with this Silver Surfer story was published in 88, anyway, it's different in the sense that Norrin was doing that because he feared that since Galactus had imprisioned both him and Nova in the planet, Galactus would just pick random planets to consume regardless of whether or not there were sentient beings on it, so he made the deal with Mephisto so one of them can become Galactus' herald once again to save the lifes of all of those beings. So even though he was just as moronic as Peter for making the deal (And unlike Peter, Mephisto wasn't nice to him), he was sacrificing himself to prevent a bigger tragedy, and the deal was undone in the same issue. Not to mention that deal wasn't a shitty way to change Norrin's status quo, so it's less problematic than Spidey's in more than one way.
I don't see how OMD has an ambiguous ending, Mephisto got the deal, altered reality, and in this altered reality OMIT happened instead, seems pretty straight forward.Anyways,with the storyline in OMIT and more recently the story arc in Spider-Man/Deadpool, that actually made the OMD story one of the stories with ambíguos endings to have the most sequels to have those ramifications resolved,thus me being surprised to still see fans saying the OMD is still not over.
Stories with super heroes against ultimate villains types as Mephisto or Shadow King many times have ambiguos endings thus why i was not one of the readers that after OMD was published thought there would be a sequel to that story but was nice to see how the unanswered questions about that story were pretty much all answered with the One Moment in Time story arc.
So i did look as OMD another story with a ambigous ending (something common in stories featuring villains as Mephisto) and now with OMIT and Spider-Man/Deadpool makes the story of OMD to be over IMHO.
I also don't see why fans want OMD undone so much, it's not like undoing it would magicaly improve the writing, and if the marriage is brought back, that Peter and MJ will be well written in the relationship, honestly, OMD doesn't even need to be undone for those two to get back together, they just can't marry because of Marvel's childish attitude towards aging Spidey.
