It's interesting. Not the photo, my reaction to the photo. I like Cavill a lot. I think with good material, for instance where the good material popped into Man of Steel (character material, specifically - I liked a good chunk of the hard sci-fi elements) he really shines as a really good Superman choice, and I like his more modern, natural feeling Clark, too, heavy-handed philosophical thesis statement or not. I actually like that bit of silver - although I can't see why they didn't just make it an actual belt rather than something belt-esque that serves the same design function.
So really, the subject matter is not a problem, it's rather how it's presented.
The "stylistic" flourish - and I say stylistic in sarcasm quotes because frankly, it's not very effing stylish is like straight outta Injustice: Gods Among Us or other modern RAD, BAD and totally generic video-games. So you know ... Zack Snyder-esque, which to be honest I thought the promo material for Man of Steel actually avoided with its fairly clean presentation.
What does it convey, setting him against that dismal, Gotham-esque (but not good Gotham ... video-game Arkham City Gotham) kind of vibe? Obviously that the social ramifications of Superman will be at the forefront of this film and that Batman will be used as the character to, ironically shine light (or shine darkness ... darklight?) onto the function and ideals of Superman. He'll be our skeptic (while Luthor will be the outright cynic). Superman will no doubt win Batman over by the end. Probably with a bit of help from Lois Lane and Alfred.
So you can understand exactly why that atmosphere was selected for this image.
It's just ugly. The colors don't pop. The somber tones strip the chic and avant-garde style right out of it, which defeats the point of having Superman in the image. Frankly I've always felt that aesthetic strips the chic and the mystique out of Batman as well (I prefer the high contrast noir to the desaturated faux).
I don't expect that aesthetic to carry into the film. Snyder & WETA's Krypton was colorful. Kansas was green/tawny, steel and cinders, and sunkissed. The arctic didn't have too much of that "teal/blue" color correction to make it seem "cold" - it's snow, man. It already feels cold. Man of Steel, probably thanks to the Nolan influence, was right to put these extraordinary beings into a nearly totally "realistic setting".
But if this is where they're going with the posters, I'm going to have words for the presumably one-time art students in their COM-D department.
