I don't read comic books anymore because of retcons like this. They often don't seem natural, but instead seem forced as if short term sales make character development take a back seat. I stopped reading Green Lantern once they got rid of Kyle Raynor as the main character and brought back Hal Jordan. I actually liked what they did with Hal Jordan and was willing to read The Specter for the first time with Hal Jordan being the protagonist. I was interested enough in the new character to purchase the new Green Lantern. I felt that moving on brought depth to the comic titles, even if it meant altering the main character because he had matured past further development in the current story arc.
But sometimes it feels as if they just try to recycle the characters without any character development. Bringing back Hal Jordan and putting Kyle Raynor into the background for instance.
I stopped purchasing Punisher once they made him into a servant of Heaven and reduced his age to that of someone in his 20s.
Maybe I'm being unfair, but I don't think comics are doing well, and the latest moves by DC and Marvel seem desperate. I worry that trying to be 'edgy' to bring in sales matter more than writing good stories. It's ironic that print comics are suffering at the same time that movies are doing quite well.
I stopped purchasing Spider-Man after One More Day, even though I loved what they did to the character up until Aunt May was shot and he had an 'edgy' fight with King Pin and donned his black costume again. Then One More Day happened and I can't ever go back. If Peter Parker was living with his new identity exposed and having to adjust to life because of it, I would have kept buying the comic. If Marvel felt he had gotten too old, for the younger crowd, it was ok because he was aging with me. I have a wife and kids now, and I identified with Peter Parker maturing.
Somewhere out there, there is a Peter Parker that has his identity known to the world but serves society professionally as a scientist and teacher. He has an Aunt May that is accepting of him, despite her initial fear of Spider-Man. Flash and Black Cat are a couple, and closer to him despite their conflicted and emotional younger days. He has a daughter named May, and had to fight the Green Goblin in a climatic battle to get her back. Life is no less complicated, and he makes mistakes, but he is still an inspiration.
