This new trailer looks vaguely more interesting than the last one, which seemed to be advertising "Gritfest starring Edge McDark" instead of an actual movie.

On the downside, there doesn't seem to be much left to look forward to, thanks to the heavy spoilerage others have already noted. Previously, it looked like "Bats vs Supes" was going to be the central conflict of the whole film - hence the title. Now we know that's probably not the case, so any surprise is automatically gone.

I still like the casting of Eisenberg as Luthor, though, because of how much it subverts fan expectations. So tired of people whining that he must be portrayed as old, bald, and buff, because he's always been that way. Since the day he was born, apparently. And because a human needs big muscles to be taken seriously as a Superman villain, because big muscles mean he could totally be a physical threat to the godlike alien.
