It seems like the conflict between Superman and Batman is really really forced.
It also begs the question of why the Bat is so upset as Superman for doing his best to save the world when he was Batman and during the whole Zod stuff he did...nothing. Of course he could be reminded about that 4 megaton fusion bomb he let the League of Assassins get a hold of before he disappeared, and having countless people die in Gotham in the last movie.
