Comics companies had to resort to gimmicks to sell books,
As opposed to the early Silver Age, when comics were sold with dignified premises that aren't at all gimmicky in the slightest, like Superman joining the army, becoming king of giant ants, or Lois Lane becoming a centaur.
Actually, I see Superman's history as a U-shaped curve: gimmicky in the fifties and early sixties, then acquiring and telling straight science fiction stories, and then going back down to gimmickry even worse than Otto Binder and Weisenger ever dreamed, with electric Supermen, multiple Supermen, and Superman's marriage.
As bad as 1990s Superman was, he was just doing for real what 1950s Superman did for fake. If there's a difference at all (and there is surprisingly little), it would be that.
1990s = 1950s!
May the SCHWARTZ be with you!Post-Crisis continuity was more autocratic, and these dicatorshippy qualities led to its collapse. It was decided in the very beginning what continuity would be, and editors enforced it.
...as opposed to Mort Weisenger, who was well-known for his openness to writer suggestions and his "hands-off" editing style.
Really now, I don't think the problem is that 1990s continuity is autocratic. Whatever contempt I may have for Helfer and Carlin and their inability to understand the character, I *like* the fact they created a consistent world with consistent elements: the Eradicator, Black Zero, and all that. It wasn't good, it wasn't Superman...but by God, it was consistent, it had a distinct feel and an internal logic. That's better than nothing.
Continuity NEEDS to have an immutability in order to be truly successful. That doesn't mean there can't be a little wiggle-room, certainly: if someone has a plausible idea for, say, how Count Nefaria has a daughter. Continuity can't and shouldn't be a Wikipedia-history which can be edited willy-nilly. You can't suddenly have a fifth guy on the Fantastic Four's rocket-flight that wasn't mentioned before.
If something isn't immutable, it doesn't have weight because it can (and will) be changed around. If it doesn't have weight, we can't seriously accept what we see as being "real." If we can't do that, we can't care about characters long-term. This is why the current Marvel business about Skrulls infiltrating earth irritates me: if anybody can turn out to be a Skrull at any moment...anything can be invalidated by saying "A-ha! Mary Jane was a Skrull from issues #487-515!" It's a really dirty trick.
A general rule is this: if it "feels" retroactive, it probably is a bad idea. The idea the Amazon Zamorans have a connection to the Guardians, for instance, doesn't feel retroactive. It makes sense, and is a connection that we just never saw before.
And really, this ability to edit indefinitely by writers led to some of the absolute worst excesses of the early Silver Age. Nonsense like Superman having a twin his whole life that was never mentioned and a monkey stowing away on his rocket.
