My personal favorite is Brosnan. To me, the guy is a living embodiment of what I feel James Bond should look and act like. Does that mean I reject any other interpretation of him? Not at all. Does that mean they're "wrong"? By no means. I can enjoy the other renditions just as much for what they are.
Exactly. My sentiments as well. As I mentioned in a previous post, just as much as a lot of people despise this rendition, I've seen and talked to numerous people who say they NOW like Superman and think the character is exciting because they can relate to him being that he has a definitive arc. Any previous take they felt was just "meh". A little too boring.
Like you, I feel the core of the character is still demonstrably there. In fact, in my opinion, I think they're really trying to drive it home more now in this current rendition than any other previous one based on what I see. Just my opinion. His character is essentially at the forefront of BvS and is what makes the movie go.
In the MCU, they're essentially doing the same thing with Cap. He's probably the Marvel character that is least relatable to people because he's TOO good and doesn't possess any of the same everyday relatable "flaws" like the characters you mentioned. When someone is too good, we tend to question their motives, as if there has to be some sort of catch to it because nobody is just that intrinsically good. BvS dealt with this also. Like that article said, people tend to lose faith that such a hope or a true goodness actually exists anymore.
However, they are taking Cap and integrating him into our modern world and presenting him with today's issues. The same issues that we face. He even expressed himself in TWS he was getting confused on what "right" and "wrong" actually is now. But with this portrayal of him, the core of the character is very much there.
