My main problem with Superman is Superman himself. He can't be killed, he has awesome powers. Is he brave? Doesn't count, when you can't die, you have nothing to fear, so in essence, you don't need to be brave. People around him can and do die though. However, when you have virtually unlimited power you can sure protect them until natural causes take effect.
I wish I was smart enough to draw a comparison to Marvel's Hulk character "Maestro". However, there is some kind of comparison there.
Emotions for Superman, teenage Supes? Oh man, the character's outlived himself. It's time for an end to the character, let him "live" in his history and our memories. Find some way to have him fight an epic, terminating battle to save humanity, then die, really die, not come back, ever.
