While I agree for the most part on the Doc Ock turn, I gotta disagree with "One More Day".
I don't hate "One More Day" because it's ridiculous, poorly-executed, and reeks of editorial mandate. I don't hate it because it results in a lot of mind-bogglingly stupid retcons that effectively give the finger to JMS's work on the series.
No, I hate "One More Day" because during JMS's run, I came to the realization that Spider-Man had been a kid for far too long. He needed to grow up and evolve. He needed to stop talking about responsibility and finally own up to it. And I was totally on board with this.
So when Peter is faced with mounting adversity from his friends and colleagues over the "Civil War" stuff, his beloved Aunt is knocking on Heaven's door, and his life as Peter Parker is thrown to the chopping block after revealing his identity, I thought this was the perfect opportunity for his character to finally hit a milestone.
When Mephisto showed up and offered him an easy way out for a (let's face it) meaningless price, I thought this would be the perfect moment for Peter to prove what the meaning of responsibility was. By rejecting Mephisto's offer not because it wasn't a good deal but because it meant running away from his problems for the sake of his own selfishness, it could have been probably one of the best moments in Spider-Man history. A defining moment.
But then, nope. Peter took the deal. All of his complications and problems? Swept away in an instant. All so that Spider-Man could go back to the way he used to be. He went back to living with Aunt May, his dead best friend came back, he was single, his new powers were gone, and we didn't get so much as a hint of regret from that supposed part of his soul that still remembered what he did.
The thing is... I related to Spider-Man in the events leading up to "One More Day" in a way that I hadn't since I was a kid. I could understand the struggles of responsibility and consequences that come with growing older. And it's not just that I can't relate to the younger, free-spirited Spider-Man or anything, it's just that I can't relate to a guy who, when faced with the problems of the real world that resulted from HIS choices and HIS mistakes, opts to sacrifice something that matters to him in order to cling onto simpler times that he should have grown past long before.
To me, "One More Day" felt like the story of a guy who married young, found out how hard it was, and then opted to get a divorce and move back home to live with his parents because those were the "good old days".
I can understand wanting to keep "Spider-Man" a character for young people to relate to, and I get that they couldn't have Peter retire and get replaced by a new kid because that rarely ever works out. But if they weren't going to have the balls to follow through on all these complications in Peter's life, then they shouldn't have bothered in the first place.
