On the subject of "Superman should save cats and smile 24/7"
The way in which people think Superman should behave depends entirely on their world view. Whether you prefer him portrayed as a perpetual source of constant positivity, or as someone who experiences the full range of human emotions in their position of unfathomable responsibility,
it all depends on how you view the human condition and what you're looking for in your entertainment.
Maybe you're oblivious to the chaotic nature of our species and just want to have a good time at the theater. Maybe you choose not to concern yourself with the suffering of hundreds of millions of innocents elsewhere; or maybe you're fully informed but seek out a different reality in the escapism you consume. Perhaps you want to see an Atlas like figure shoulder this burden of power and face these harsh truths head on.
These are all valid subjective preferences.
Oftentimes when it comes to discussing comicbook heroes, people value the relatability of a fictional character above all else.
However, this has different meanings from person to person, does it not? We want something to aspire to be, but these aspirations are not universal. Someone is completely entitled to disliking God-figure characterizations and preferring an upbeat smiling Superman
, but to someone else that won't make sense. To that second person they'll think: "how is a constantly upbeat Superman relatable?", do we not face anxiety and pressure in our everyday lives? That second person will also think: "What's he doing saving cats? what of the countless other crimes and atrocities that are happening simultaneously, and if this upbeat Superman has already solved them then how can someone so perfect NOT be considered a God-like figure?".
The point is there is no point in arguing which portrayal is outright superior. People will like what they like because when it comes to this subject, it appeals to us in different ways on such a fundamental level. To one person, what's inspiring is thinking that there's a likeable hero selflessly overcoming any obstacle; to another person what's inspiring is thinking there's someone out there, powerful but one of us in spirit...imperfect but giving his absolute all to fight for what's right.
