Killing this Superman in only his second appearance seems a bit....well I don't know what to think of that. On the one hand it means that Doomsday isn't entirely wasted, he does the thing he's known for doing - just, in the original story, correct me if I'm wrong, Superman was already loved and embraced....whereas it seems like in this film the intention is that only by ''dying'' for us does he become loved and embraced? Hmmm....well I'll have to see how this plays.
In other words: damage control in its ugliest form.
But if it's good for the narrative then I'm fine.
