Exactly. It doesn't parallel the story of Jesus in every way or even in most ways. It just implies the similarity at some key points.
Personally, I realized how ridiculous it was during Superman Returns. I'm not a hater of SR. I think it had some great moments and some bad ones and some of the great ones for me, someone else might dislike. But they got into all the stuff about how the world is crying out for a savior. So, you've got Superman drifting in orbit listening to all sorts of stuff happening in the world. The imagery of "God" listening to the prayers and cries of humanity is blatant. So, I assume Superman hears the cries of starving children, of people in poverty crying out for food, and on and on and he does absolutely nothing. What does he respond to? Some bank robbery that means absolutely nothing in the overall scheme of things, that isn't going to do jack s**t to change the world or alleviate any suffering.
I suddenly realized the problem I have with that sort of imagery even when I liked it at a more subtle level with Donner. Are you really going to present this guy as a world changing messiah or as a superhero in a cape in tights? Either could be a great story but choose one. Because the message that scene delivers to me is the all too unfortunate one that, by savior, they mean "champion of the status quo, defender of bank presidents, hero of the meaningless".
Now, I wouldn't even think such thoughts if Superman was just fighting Luthor's latest world domination scheme but these movies set him up to be far more than they are ultimately willing to let him be.
Give me the Golden Age Superman and the scale of power he existed on any time because he actually delivered and was what he was proclaimed to be: champion of the weak, defender of the oppressed. And yes, he still found time to stop bank robberies.
