I think some of you might be missing Dragon's overall point. Take a closer look at his statements:
Dragon said:
Sure, there have been some excellent stories/arcs. But there have been no characters, or development of existing characters that have been an actual evolutionary contribution to the mythos.
He's still too much like the kid he was in High School and College.
When Stan developed Spider-Man, he didn't simply create events. He created lasting change and as I mentioned evolutionary elements for Peter.
In other words, he's talking about CHARACTER DEVELOPMENT, where, because of the events he was involved with, Spider-Man, as a character, changed either in terms of his attitude, outlook on life, how he dealt with others, or just becoming more mature, not so much physiologically, but mentally and emotionally.
For example, anyone remember the end of the Spider-Man animated series from the 1990s? Spider-Man tells Stan Lee that, despite everything that has happened to him, he still feels pretty good about himself and who he's become, to which Stan responds "Wow! That doesn't sound like the Spider-Man I've been writing about all these years," which was exactly the point. It showed that Spider-Man DEVELOPED as a human being. Likewise, during the first issues of Amazing Spider-Man, including his origin in Amazing Fantasy #15, Peter started out as a shy, bookish teenager who, while brillant and friendly, was never appreciated by people his own age; in fact, he quite resented them for always giving him the brush off. After getting his powers, he decides to capitalize on them by going into show business where he finds acceptance. With the exception of his Aunt and Uncle, Peter basically only cares about himself, saying that "the world can go hang for all I care," which comes to a head when he lets the burglar escape. But then, after his uncle is killed and Spidey learns that it was committed by the same burglar, he realizes it the most painful way possible that he should have used his powers to help others rather than for personal gain. At first, he tries this by STILL BEING AN ENTERTAINER to raise money for his recently widowed Aunt May; but when J. Jonah Jameson blasts him in the Bugle and Spidey can't get anymore gigs or cash his checks, it's then he tries to become a superhero--in order to get more entertainment gigs so he can get more money in order to help Aunt May. But when he's still blasted by Jameson after rescuing J.J.J.'s own son, and, when trying to join the Fantastic Four, realizes there's no profit in being a superhero, that he learns that the life of a hero doesn't necessarily mean adulation. Likewise, by battling various criminals and supervillains, learning how to fight, utilize his powers and equipment, and throw out snappy one liners, he grows in confidence as Peter Parker, is more outgoing, is able to stand up to guys like Flash and Jameson, ask girls like Betty Brant, Liz Allen, and Gwen Stacy out on a dates, and becomes more confident in himself. His encounters with supervillains make him understand that he can't always rely on his powers to save him or that he should throw in the towel when he's defeated. By the time "Spider-Man No More" happened, Peter was willing to give up the life of a superhero to regain some scene of normalcy in his life, but soon learned the the value of personal sacrifice for the sake of others. As he was a teenager becoming a young adult, graduating high school and going to college, he was also learning what it meant to be a man and LEARNED from his experiences.
But then, as Spider-Man became more popular, it seemed that there was a tendency for writers not have Spider-Man EMOTIONALLY grow up, evne though, ironically, they kept having him PHYSICALLY grow up. Even his powers developed more than he did emotionally, especially in the last couple of years. Sure, when Gwen Stacy died, he became darker until Mary Jane helped him to cope with his loss, but did he worry that his getting involved with another woman might lead to her suffering the same fate as Gwen? Not really. Sure he confronted the burglar years later and realized revenge wasn't the answer, but did he stop blaming himself for his Uncle's death? Not really. Sure his relationship with the Black Cat made him realize that his trust in people could be exploited, but did he learn to become a little more suspicious of others who flatter him...like Iron Man for instance? Not really. Sure his experiences with mystical spider totems (as well as other cosmic and supernatural enities) make him realize there is more "out there" than he may have realized, but has this made him see that there are things that science can't explain or that it's not always as reliable as he might think? Not really. He keeps repeating the same mistakes and having to relearn the same lessons.
Even though he's "aging"--and even though there are those who think that's a mistake in itself, especially with regards to his getting married and the possibility of him having kids--he's not "growing" as a character, perhaps because there is a certain "template," a particular characterization of Spider-Man that the comic book creators want readers to identify with, even though, in most fiction, characters are not emotionally static and learn from past experience. And whatever attempts have been made by writers like Gerry Conway, Marv Wolfman, and Roger Stern to make developments in his character, there are other writers who retcon these developments away and end up having Spider-Man regress emotionally, which is why we get things like The Clone Saga, [blackout]Sins Past[/blackout] or Spider-Man Unmasked where he seemingly acts out of character to conform with the demands of the story so that he can learn "valuable life lessons" that he has already learned time and time again. But, I guess that's the price one pays when dealing with a serial character in a non-finite series.
