OMG!!!! OMG!!!! OMG!!!! that is all,move along now!

Superman is a crap character. DC should phase him out of existence if it wants a shot to be like Marvel.

In fact, they don't need anything else than Batman and... whatever manages to fit in the same world.

Judging by what I just saw it appears Lex Luthor sort of takes Superman under his wing (the scene where he's bowing to him) and gives him command of the Super task force we see (the guys with the symbol on their shoulders) basically putting him to work for Lexcorp or the US's benefit and tricking Supes into thinking that's the right thing to do. Lex sends him to take down the vigilante in Gotham as he doesn't like an unknown quantity like that. Batman has already seen the destruction and doesn't trust the govt./Lexcorp so he decides to build a super suit to fight the alien and his men. The only thing I can't figure out is how Wonder Woman figures into this.

It is a good first encounter, not the best, not the worst, but once again the problem with this movie is that they are making the fight the central part of the plot, and that is usually a minor part, the writer does not understand the character and he alredy prove it in MoS

Well Chris Terio (writer of Argo) was brought in to rewrite Goyer's original script, who wrote Man of Steel. I have much more faith in him than Goyer and from the trailer it looks like Lex is manipulating Superman and Batman to fight each other. Also, it's probably much easier and smarter to market Batman vs Superman as opposed to Lex being the true villain.

Yeah, this is clearly setting up for a Justice League movie (or trilogy, more likely)

I hope he gets the character better, but from the trailers I really doubt it. Goyer is a good Batman (and some other dark characters) writer, but he is a very poor superman writer, they really need to show the contrast the light vs darkness thing they mention in the trailer, it needs to show, but currently I see the dark vs darker heroe only, and is depressing as hell, very low expectations for this movie.

I think the exact opposite.  Lex stirs up the Senator (he tells her Supes is dangerous) and Batman to go after Supes, no doubt using the Supes-worshipping zealots to "prove" he's a threat.  All the dialogue in the trailer from Batman and Alfred point to Batman being the aggressor, not Superman.  Lex even makes a reference to Superman and his forces as the "red capes," a play on redcoats, implying he is "warning" Bruce and the gov about the "dangerous" Superman.  As for that one scene with Lex, he does not at all look like he is friends with Lex; he looks super pissed.  We see a scene with kryptonite, he is likely feeling the effects of that.  As for Wonder Woman, I'm not sure either.

Batman being jealous? Sorry but nothing points to that being the case. From his perspective, there's a superhuman who wrecked a huge city and killed people he was close to.

Superman might have saved Earth from an alien invasion but that doesn't mean we should live on this Earth by his grace. What happens when he gets angry? Last time that happened, he co-destroyed half of Metropolis.

As for your smaller points:

- Agree

- Alfred is a very cool character.

- Well, Batman is supposed to be massive.

How can you have a prequel without have the movie that it is a prequel to be out?
