Many of those are terrible terrible changes. Aunt May turning evil for example...
As anyone who is following the book regularly knows, the Aunt May change was temporary. I cited it to refute an earlier post that the book was only doing "rehashes"-- which it's clearly not.
And even though the Aunt May change only lasted a few arcs, it did advance the story, and readers will be seeing a repercussion from it later in the year.
Brand New Day retconned major deaths...
1. OMD was the story that changed the status quo. BND stories were by a different editorial and creative team.
2. "Deaths"? Plural? The only death that was undone was Harry's.
Harry should still be dead. Period. There was no reason to bring him back.
Characters that are off the canvas can't tell new stories, characters that are on the canvas can. I would've said the same thing about Norman Osborn's "death". But since he's been back he's been part of some great stories. Same thing for Aunt May. One of the JMS stories that you say you liked couldn't have happened if she'd stayed dead.
And going by the positive reaction and tons of fan mail we've gotten on Joe Kelly's AMERICAN SON arc, there'd be a lot of fans who'd disagree with you and think that there was plenty of reasons to bring Harry back.
Like so much of Brand New Day, one of my favorite Spider-man tales ever was sullied by this horrible retcon.
Things that were great that Brand New Day Killed...
1. OMD was the story that changed the status quo. BND were the stories that came after.
2. When you start to say things like how a story was "sullied" or how things were "killed" it gets a little silly. Who the hell says "sullied" anymore? What? Were you fanning yourself on the veranda of your Southern plantation, perusing the latest Spider-Man periodical while sipping on a mint julep? "Lord have mercy! They have done brought back Harold T. Osborn! Why I never! They have SULLIED the good name a' Marvel Comics! I shant stand for it, y'hear?! Fetch me my pearl-handled pistols! We shall duel at the setting of the sun!"
Aunt May knowing Peter is spider-man. That was one of my favorite developments of the past 10 years.
1. Shouldn't Aunt May have stayed "dead" after ASM #400? Doesn't that break your rule?
2. Those stories still exist and they still happened.
3. Even before the unmasking, too many people knew Pete was Spider-Man in his supporting cast. And during the years before BND, Pete's supporting cast had kinda shrunk down to MJ and Aunt May. It got to the point where Pete didn't have a civilian life and relate to people as JUST Pete.
Death of Harry Osborn- Harry had a fantastic death, and it was one of my favorite spidey stories...why the hell should they do away with that.
That story is still there and it still happened.
The marriage- The fact that marvel can't write a married Peter Parker shows an overwhelming lack of imagination, and complete cowardice.
Marvel CAN write married stories about a married Peter Parker. A lot of the current Spidey team has. They're choosing to tell new stories about a single Peter Parker. And despite the insult of cowardice that you'd like to throw out there, I think that it's obvious from your ire, that the exact opposite is true-- that Marvel knew it was taking a huge RISK by taking the marriage out-- but that it was a necessary thing to do for the long term health of the franchise.
