Eh, it would be cool if it's the result of a serious physics/fluid simulation. But I doubt his boots act like wingtips.
Absolutely horrendous teaser. Dark, moody, depressing, pretentious, much like Nolans Batman trilogy. The difference with Batman is that the dark tone fits the character of Bruce Wayne/Batman. The Avengers made over 600 million at the US box office, proving that good (superhero) movies needn't be this dark.
I hope they at least go the Superman is a bright light in a dark world angle.
