On the other hand I wonder if they are going to release a second trailer from the prospective of Superman thinking the same thing about Batman, in other words each thinking the other is the issue that needs to be dealt with but then both coming to the realisation that they are in fact two sides of the same coin.
I really hope the second part above is what's actually going to happen, if not and it just turns into a Batman has to show Superman what's right and wrong then I am not going to like it at all. 
Are you kidding man? It's superman. He's the all american boy scout, the goody goody!
It seems like he's getting a lot of respect in this movie (swat team kneels at him), and I don't think Batman likes it. Batman might presume supes has an ulterior motive maybe? With all that power, well, batman is obviously going to think the worst.
It's been confirmed they share a handshake in the movie. So they'll have a scuffle, and then realise they both have the same goals, and then they'll start to work together.
Liking the darker tone, batman just looks so goddamn incredible, even though you don't see much of him and it's in SD. I have to say, this looks on a whole other level when you compare it to the light-hearted tone of the marvel movies. Some of the scenes in the trailer were beautiful.
Hope superman IS superman though. I hope he doesn't let people treat him like a god. Should be treated as equals. And I'm also worried about wonder woman now. Hope she's not crap.
I mean it is being portrayed as Batman centric movie with the main voice over being batman
Batman only speaks at the very end. "Tell me, do you bleed? You will."
All the other voice overs are news reporters, lex, and possibly alfred.
