Legitimate point, understandable Superman wants to learn about his past....MOS will surely explore this as well...BUT...
Superman is an adult..not a teenager....and his inability to consider consequences of his leaving Earth or inability to communicate that to loved ones...is just not excusable. Just because you have needs doesn't mean you can just ignore everyone else's and look clean.
I was actually talking about MOS and in reply to the person who said MOS Clark seems to be more "selfish" than the Superman from SR.
Yeah, leaving and ditching without a word is kind of careless and a plot hole in those regards. But, I can say I'm okay with the kid there. A lot of what adoptees, or at least me and I think Bryan Singer, yearn for is that biological connection. It's the one thing we don't have and many others take for granted. Often an adoptee who has a child says that it's like they finally feel grounded and like there's a gravity there rather than floating up in space. So, Superman getting a son really struck a chord for me and is why I think Singer went there as well. But, leaving without a word didn't really feel true to character.
From what I've seen, this Clark is going through an identity crises, keeps to himself and travels all over in search for his identity (I've so far lived in Long Island, Los Angeles, and soon NYC all in search of "trying to find the place for me" - unsure how many others have gone through this, but this side of the character I can definitely understand), and wants answers to questions a lot if not all adoptees have. And there are some people who have seen this as selfish which I'll never understand. And those bringing up selfish in MOS' case, wondering if it's more their views. Because, as said, Jason's character in 'Place Beyond the Pines' was really relatable to me and one of my friends who's also adopted - but in the theater, IMDB, and here I've heard people calling him "selfish" when all he did was search. Which to me says people might be bringing their own 'beliefs' (no matter how informed they are) into 'searching' movies because they can't really grasp the yearning of it. We don't search to hurt, we don't want anyone to get hurt, we search to heal.
'Place Beyond the Pines' is actually a perfect example. Because for that movie I saw two distinct reactions. People calling Jason a jerk and selfish. While those who don't know either both or one of their parents related to it and stated it really got to them and rung true. It was a clear distinction to me of people who have no emotional stake in knowing that that's like calling it selfish, while those who have experienced it calling it real and great for the film to go there.
