Grant Morrison turned Superman into a douche bag. I still don't know how the man who an AMAZING story about Superman going back in time to make say goodbye to his father could turn Superman into an entitled, whiny, dickish, Batman rip-off.
This is Superman at the beginning of his career, before he's learned how to be the great hero he will be in the future. He's not a douchebag, he's just young and naive. You can't expect him to be perfect right off the bat. It's an interesting take that harkens back to his Golden Age roots.
