It's true that Stan Lee didn't write women well, and that's the primary reason why Gwen came to be seen as disposable. You know there were a lot of attempts to write Sue out of the FF. Like people tried to make the girl on the four at various times -- Crystal, Medusa, and so on. If you are saying that Gwen Stacy could have been rounded had she lived longer, I agree with you. I think ideally Conway should have broken Peter and Gwen up, and have her leave the books for a while, and then come back when another writer wanted to revive and pick up threads. That would have worked well for Gwen.
But at the end of the day, the story that we have is what we have. Gwen is defined by the stories that were written about her when she was alive. That's the true Gwen.
Roger Stern is not in fact a pro-marriage fan. He was famously and vocally critical of Peter's marriage to MJ. But that doesn't mean he is a fan of Gwen Stacy or Felicia Hardy either as Peter's love interest. Fact is that not everyone who had issues, or have issues with Gwen's character when she was alive are okay with shipping Peter and MJ and so on.A pro marriage fan putting down Gwen must be a Monday.
Read the story, ASM #91-92 and decide for yourself.
Any case, I think people are right and that I might have overstepped in posting so much. It's just that when people say Original Gwen Stacy, I kind of assume it's the issues with the character written until ASM #122 and not the Gwen Stacy across Spider-Man media.
