So as not to get into a circular convo about production quality or editing issues etc, this reply is only about my observations of the portrayal of the character.
Superman, in this rendition at least, IS a babe in the woods.  He is a young man who has powers and abilities far beyond those of mortal man...yet he has been taught by his parents to hide them and only has used them in times of great peril to save people from certain death.  In MOS, after he saves people, he moves on so as not to be discovered.  He IS conflicted about HOW or IF he should be using his powers at all based on his fathers wishes and warnings.  By hiding his abilities we should also consider that Clark's motive may also be protecting his Mother, realizing that her life would be drastically changed if the world found him out.  
These films view Superman as a being that has been orphaned on Earth and knows nothing about his background and is searching for answers.  He was not sent here as SUPERMAN.  He was sent here as a baby by his parents to 
survive and maybe one day re-establish the Kryptonian race (but that's another story).  He was not sent to Earth as the savior of mankind.  The people of Earth 
made him that after seeing his abilities.   That is why he is "uncomfortable" with this notion.
He was not born to be SUPERMAN.  He was born to be Kal-El, a Kryptonian boy.  Superman is a character he plays for the people of Earth to be able to use his powers in a manner that protects his identity. (and his Mothers).  
As a moral and ethical being, in both MOS and BvS it is not out of place for him to have questioned his place in this world and the reaction of humans to him and wonder if he is doing the right thing.  He is a reluctant hero, wanting to help but not comfortable with the "misplaced" worship.  
This is what I feel is the "realistic" portrayal.  Not one that simply has Clark become SUPERMAN all of a sudden, all smiles and happy to be using his super-poweres to save cats.   
Although great fun, STM, the first Donner film had an interesting conflict.  Jor-El educates Kal in the void for 11 years, teaching him all about Earth and Mankind and warns him; "It is FORBIDEN to interfere in human history"...  
He then proceeds to give him a colorful suit and he goes out as SUPERMAN to introduce himself to the world as a superhero.  Not very humbly I may add and a bit hypocritical. He has Lois interview him so the world knows he is here. Standing akimbo "I'm here to save you !" YEA!   This is a great comic book introduction of a superhero to get the ball rolling and see a lot of cool stuff but hardly a realistic approach to how people really act and react.
I think in JL, we will see a different Superman, maybe this Superman.  One that understands better the nature of people and one that accepts his role as a leader and save people "happily" knowing that he has found his place in the world.
PS:
You guys that are taunting people about "proving" or substantiating their "feelings" gotta lay off.  It really is unfair.  You can not prove to someone else why you felt something.  It is subjective.  It IS emotional.  So why don't all you frustrated pseudo intellectual Mr. Spocks out there quit acting all high and mighty and denigrating others "feelings" because you don't "feel" the same way.
