All the stories that took place—happened. It’s unfortunate that people think otherwise; the plan wasn’t to undo twenty years of continuity—Marvel Comics just chose a different direction for Spider-Man. If you want to still complain about ‘One More Day’—go ahead, I get it—but I’d rather you beat us up for what the story really is. If you want to quibble about Peter Parker making a deal with the devil then so be it. But don’t go saying that hundreds of issues of comics “didn’t happen” because they did.It really doesn't matter whether they retconned away 2 decades of continuity or not, the problem with this editorial fiat is that it depicts Peter and Mary Jane out-of-character, makes Peter look like a slacker, and if it really didn't undo continuity, then Peter and MJ are otherwise committing adultery.
I am surprised though that he admits the deal with Mephisto is a problem. Or does he?
NRAMA: But isn’t that sort of “deal” a natural human reaction—Spider-Man is just like you and I when it comes down to brass tacks, right?So he, and come to think of it, the interviewer, don't think anything's wrong with making a deal with the devil? Ah well, that's the problem with people who put money over common sense.
MG: Well, it’s still a fair criticism—even though I don’t agree with it. I definitely understand why it’s still being discussed. But when someone says, “You’ve negated all these years of stories,” that’s simply not true.
In a sane world, Guggenheim would be shooed out the door and not permitted to write comics ever again, and certainly not to give silly interviews like this.
