Ok - I just watched it again - they posted a hi-res version on YouTube -
http://www.youtube.com/watch?t=21&v=IwfUnkBfdZ4And to answer your question Jeff - no, the lack of clarity/quality of the original version did NOTHING to hurt people's impression of the movie, the trailer itself does a good enough job at it.
Like Qui-Gon Jim said, we get it DC, your universe is "dark" and "brooding" - but guess what, I also want to have a little bit of "fun" when I go see my superhero movies, so you're going to have to do a bit more than just trying to recapture the lightning in the bottle that was The Dark Knight.
And seriously - "Tell me, do you bleed?.... YOU WILL" - just HORRIBLE, is Superman supposed to be scared by that?
Oh and for anyone who was holding out hope that man-child Eisenberg was going to be decent in this film, watch the video again, he's the girly-man voice saying weakly "Devils don't come from Hell beneath us, (whisper) no, they come from the sky" - want some cheese with that wine Lex?
Unless I see something radically different in the trailers we get closer to the movie's release, this is an easy pass for me.
