Since the Nolan Batman Series, everyone thinks if they go "dark" then the Comicbook premise will garner artistic credit. With some , like Batman, it works. But you can't brush stroke everyone with the "darker tones."
seems to be taking that route, and I can't see the "biggest Boyscout" of all time being brudeing or dark, sorry, doesn't fly (pun intended).
I saw "The Avengers" the other day, great tone some "moody" moments but weren't over the top and were left at appropriate levels. Comic book films are to be fun, not all are meant to be on par with "Masterpiece Theater."
