Kinda is Superman, except he had two douchebag fathers who emotionally abused him and instilled a God complex/fear into him that left him broken.
And he still does heroic things.
"He still does heroic things" I feel is something that shouldn't have to be said...
I mean, every superhero is EXPECTED to do heroic things. The fact we have to say "well, he STILL does heroic things" on and off, at times, when he feels like it, between the scowly brooding, terrible parental talks, and awkward bathtub romps... it's not exactly a sterling commendation for his heroic capabilities.
Even Deadpool has heroic moments...
The hilarious thing about all of these super hero movies that fall flat on their face is that they are based on comics.
DC and Marvel have decades and decades of stories that are essentially completely written and story boarded. They could cherry pick the most well regarded ones and just film them exactly as they are and people would probably love them. Everybody loves Mask of the Phantasm. Just make a live action version with Ben Affleck and it's a slam dunk.
It's like they are standing in a warehouse full of wheels trying to invent a damn wheel.
And yet BvS failed trying to adapt Frank Miller's Dark Knight Returns and The Death of Superman, and couldn't do them even a fraction of the justice they deserved. Snyder even directly lifted some scenes straight from the page... only he failed to capture the emotion behind it. Just the style.
