Truth be told, I'm not crazy about any of the new 52 costumes, or comics for that matter. Supergirl's alright but her cousin's costume? Not to sound like a fashionista or anything, but Jim Lee's version of Superman looks like some poser wearing the S. It's just not iconic enough in my mind, not to mention boring. A version similar to this Supergirl's would be a lot better.
I think he looks pretty good in Unchained. Besides the red underwear had to go. Seriously. I think it does have a few too many lines and could use some work but oh well. As for whether or not he's iconic I suppose it doesn't really matter as long as he has an S on his chest, the same powerset, and saves people. Besides Superman isn't really all that relevant in this post-modern world we live in. We thrive on tearing things apart not saving them.
While I agree with you about the red underwear, but I've got to disagree with you on the rest. At the risk of sounding like a huge Superman fan (which I'm not. Honest.), he is the first superhero ever, and the template for most of the cape wearing uber powerful characters of today (Shazam, Hyperion, Supreme to name a few for example). And if you were to ask people on the street to give ten names when you say superhero, I'm betting 9 out of 10 times, Superman gets mentioned. Let's give the guy his due. As far as relevancy, I agree he's probably not the most popular but I believe that has more to do with the fact that he's not an easy character to write. Let's face it, it's hard to challenge a guy like that as opposed to Spider-Man or Batman and still keep him rooted to the ground. And finally, on the tearing things apart comment, I can see your point when the perspective is concentrated on the tabloid/reality show soaked aspect of our culture, but let me ask you this, if we love tearing things apart so damn much, why do super hero movies (i.e.. Movies where heroes save the day) do so well in the box office?
Not all superheroes are dark and gritty. In fact I would say that dark and gritty is becoming a little passť. But to emphasize my point, let me ask you a question, assuming you saw second Captain America film, would you say the title character is dark and gritty?
