That's how he came off to me too.
Was thinking about how I was raised vs how some of my relatives were raised, and it suddenly occurred to me why the modern versions of cinematic Superman is not very compelling to me.
I was raised in an high-expectations Asian household. You know, the usual - all A's, no B's were allowed, etc, but my parents also instilled in me and my sister real passion for doing good. Not sure how they managed that, since my parents aren't extreme hippies themselves, but OMG do my sister and I have a serious civil service streak. We aren't checking off boxes, we truly care and have passion for helping people. We get EXCITED about it, and have strong feelings about causes.
Whereas the high school we went to was also full of high-expectations Asian families, except the goal for most of them wasn't to help, the goal was to get the A's and go to an Ivy League. That's it, just check off the box and be on your way. You can tell those kids didn't have passion for what they were doing, because they simply didn't care as long as it checked off the box. They were missing that light in their eyes.
When you talk to my cousins, they have no opinion on anything because their parents strong-armed their opinions out of them. Whatever mommy wants them to do, that's what they'll do. One of them's in medical school so he's doing good, but he has no true passion for it. It's just something to check off. Being around them is kind of depressing because they really don't
care about anything.
That's the feeling I get when I watched Superman in MoS and BvS, and even SR to a point. He's doing good because he's kind of resigned himself to doing it. (What is the other option besides being a bad guy, and that's obviously onerous in itself!) But it doesn't feel like it
drives him, it doesn't feel like he has passion for it. And watching him is kind of like hanging out with my depressing cousins.
