I guess we all have our perspectives. I was already reading Spider-Man when Gwen died, so while I accept Mary Jane, understand how Peter could love her, and even like some of the relationship/marriage (After all, I did also see the transition into the relationship with MJ), there's still a part of me that sees her as the one who came after Gwen. Sure, it's the 7-year old kid who was just discovering comics, but I'm not sure I have a better sense of what makes a comic book good now than that kid did then.
