After seeing the CC footage, it sure seems like we'll have a good characterization story. One of things that seems to be different from the recent takes on Superman, Kal-El, Clark etc. is that this story seems to set the premise that Clark's very nature from a young age was to be a better example of what man can be. He always aspired to more.
His parents (The Kents), while guiding him to a proper moral compass, seem to fear that the world will not understand his greater aspirations. Will this greatness be of benefit to the world, or will it control it? (I think will be a central theme)
So, I'm not getting that Clark is unsure of himself. I don't get that he'll be immature with his powers (ala Smallville), in need of a singular clarifying event to have him make the right choice (death of a loved one?). What I see, and it is kind of a thumb in the nose of critics who say Superman is an irrelevant idealist (boy scout), is a characterization that says this man aspires to be great...something more for the world....as a choice from a very young age. Not an idealistic naivete, but a mature understanding that there is a greater potential for all of mankind...they just have to choose it and understand it is not the easy path. He wasn't pushed there....wasn't coaxed. It is his nature.
The only question is can the world, as cynical and untrusting as it is, accept this mindset? Are we ready for an actual man who by conscious choice chooses to be something more...a leader...someone who doesn't stand for the cynicism and mistrust?
This portrayal seems to finally portray the character in a mature, thoughtful way. Not campy. Superman is finally a man it seems.
