I would argue that in this film, he's not actually Superman... yet.
This film felt to me like this character wasn't Superman, but Kal-El. That means he's still starting out, eventually when we got further down the line he will become the fully formed Man of Steel. At the moment he's still just a rookie.
A bit like Batman in Batman Begins. He becomes the fully formed Dark Knight when he faces his greatest adversary; in the first film he's sort of just graduated.
