How didn't Superman act as Superman in Man of Steel?
Superman is not a character so much as he is an archetype, or an exemplar, or something. Superman is hope, stopping only just short of being a literal personification of hope the way Morpheus and Daniel are personifications of dreaming in
Sandman. Superman hopes not only for himself, but he is hope for everyone else: He is the hope that, as you are falling off the roof and the unbreakable grip of gravity is pulling you down to your death, something or someone impossible will happen to save you.
Man of Steel likes to talk about hope, but its actions do not suit its words. Kal-El does not dare to hope that things will turn out okay. Instead, he broods and skulks and hides himself away, living in constant fear not of the world but of what the world might be or might do, and if hope is a perception that the future might end well, then fear of it ending badly is the very opposite of hope. Even after he's donned the suit, Kal-El takes no risks in the name of hope, perhaps best exemplified by his decision to kill Zod: Kal-El could have responded to that situation any of a dozen different ways, whether covering Zod's eyes with his hands or flying up into space or using his obviously superior leverage to turn Zod's face away from innocents or just asking him, "Look, dude, as much time as it's taking you to just look at these people you're threatening to kill, it's obvious you're trying to force me into killing you. Do you maybe want to just talk about your problems?" Instead, he lets his fear of Zod's actions rule him and he makes a decision to kill.
Likewise, no one in the world of
Man of Steel has any reason to believe Kal-El will save them. He won't. He will tear through major metropolitan areas like the villains he opposes, causing billions of dollars of property damage and killing thousands, because he does not give a damn. He doesn't care. He doesn't like humanity, let alone love it. He saves...what, two people? Some army guy, and Lois Lane? Everyone else has to save themselves. For all that Jor-El talks about Kal-El being an example to others, you'll note the only humans to act compassionately and risk themselves to help others are Perry White and Jenna Olsen, people who never saw Kal-El save anyone and who couldn't have been inspired by him. They were already better than Kal-El before he ever got there.
Finally, Superman is not Kal-El, like this movie thinks. Superman isn't even Clark Kent. Clark Kent is Superman. Clark Kent is a boy who was raised as human by good, human parents, who grew into a good, mostly human man. Superman is the disguise he wears, not the other way around. Superman is a super man because of the man Clark Kent is, not because of the super powers Kal-El got as an accident of birth.
Also, not for nothing, but Superman didn't act like Superman in
Man of Steel because the movie is so ashamed of Superman as a concept it won't even let the movie call him that, and when it starts to do so, it does while apologizing for it.
