I'll start here. Up until 1986, Superman was more a character that slowly evolved than a character who was rebooted. Reboots didn't start until COIE in comics, and they haven't stopped since then. The Barry Allen Flash was not a reboot because the existence of that Flash did not delete the existence of the Jay Garrick Flash. What was done with Superman from 38-86 was a natural evolution where the core principles that Siegel and Shuster established were kept and expanded on. Not because DC respected them, but because what they created worked so well.
Both of those stories fit and are beautifully evolved from what Siegel and Shuster created. Siegel wrote Superman for years, and wrote him again in the Silver Age-in fact, he wrote his best stories in the Silver Age. So both of those stories were written with Siegel's Superman.I agree that many writers have not known what to do with the character, and Superman has suffered during those times. But there are so many out there who LOVE him. Should they have to handicap their stories to fit the mold of 1938 Superman? Should Morrison have not written All-Star the way he did? Should Moore have not given Superman the sendoff in Whatever Happened...the way he did? Because Siegel & Schuster never imagined Superman doing those things or acting that way. Perhaps instead of trying to save the Earth, or instead of saving a baby sun eater, or instead of creating life itself, Superman should have spent that time destroying businesses that put people out of work. Because nothing helps the little guy quite like destroying the town factory. Maybe instead, he could have educated them about the bad cars they were making. I have not read this story, so I apologize if he did; but the way you described it, it just sounds like he took the place down.
It has nothing to do with any era of Superman apart from Post-Crisis. There is not a single trace of anything from 38-86 in MOS: the Superman in it has no morals or ethics, there is no nebbish Clark Kent, no utopian Krypton, and no moral mentor in the person of Jonathan Kent. MOS would make a pretty good origin for Ultraman, however. That's the only way I can accept MOS, is if I consider the heartless murderer who is called Superman in it Ultraman.And this brings us to "Man of Steel". An amalgamation of pretty much all eras of Superman. I guess it sucks for some that the 100% 1938 version was nowhere to be seen, but you know what? Neither was "my" Superman. This does not mean the filmmakers "don't get the character." It means that you didn't get the version they presented. I really don't think audiences want 1938 from a Superman movie. If they want powered down, vulnerable heroes, they have Marvel films for that. But people don't think "factory wrecker" when they hear Superman's name. They think of flight. Who doesn't wish they could fly? It's such a large part of who he is as a character. It's wish fulfillment. It's......not the 1938 Action Comics #1 Superman.
Actually, when STM came out, Siegel had suggestions for how it could have been improved, so I would expect they would have a similar reaction to MOS. And the reason Superman has had a 25+ year decline is because they stopped thinking of what Jerry and Joe would have done.I don't know Siegel & Schuster personally, or their heirs, and I don't think they and I are friendly enough to use first names as if we were old drinking buddies. I also won't waste my time imagining what "Jerry" or "Joe" would have said/thought about the film. I would "bet", for lack of a better term, that they would both be in awe of the fact that a character that began under their pen 76 years ago has the 2nd most recognized symbol on the entire planet today...and I would, again for lack of better term, "bet" that they wouldn't mind that the symbol is not even their design.
It's been 60 years or more since they stopped working at DC, right? Let's stop thinking of what "Jerry & Joe" would have done.
Well, when I say "by your logic", I of course mean there is no logic because claiming that Philip Wylie actually created Superman is, IMO, absurd.
