The thing about Synder's Superman is I think it misses the crucial core that makes Supeeman who he is; his family's love and compassion. In the comics, Superman is just the identity of a Kanas boy who realized he has god-like powers, so he puts on the pajama outfit his mother made him and goes to help because the way he was raised tells him that's the right thing to do. Different adaptations handle that in different ways of course, but this movie's take on what seems to me as trying to humanize them damages Clark as a character.
While it's clear Clark was raised with love, it's seems that instead of being raised to see the good in humanity, he's raised to distrust it. The constant bullying and being told that sometimes it could be the right choice to let innocents die, to the point where he is told to stand by and let his father die, wouldn't make Clark become Superman. That would make him a man who would be completely secluded and keep only to themsleves. And while there could be potential narrative strength in Clark still choosing to help humanity through it all, that's lost as well and poorly communicated throughout. The scene in B.V.S. where he claims to be doing what his father always wanted makes no sense with all these points. No, that's what most verisons of his father wanted, but in this verison Pa Kent was a cynical man. He's doing the opposite of what his family wanted, and if I remember correctly, his motivations for why are never explored.
That's why I think this Superman comes off as unsympathetic to everything, at least to me. They took out the aspects that made Clark the "man" and in focusing in all the action, he seems more alien then ever.
