I think the reviews are kind of justified, personally. I enjoyed the movie, but Christ it was a mess structure-wise. The fact that the two fought so late into the movie, without having any relationship between them, is really strange to me.

One of the weirdest parts is that right before they face off, Clark calls Batman "Bruce," and it isn't justified. We never see Clark learn Batman's identity, and they have NO friendship at all. They could've allieviated this by doing something like in DKR, where Clark goes to Bruce and tries to talk him out of it. But instead, he calls him "Bruce" because that's how Superman talks in DKR, and Zack Snyder loves him some DKR.

In DKR, this fight worked because neither of them really wanted to be there, and it was sad seeing two old friends forced into a fight to the death. In the movie, it's overlong and has no stakes. We know they're gonna work things out, and team-up to stop Doomsday.

And plus, Superman has something VERY important hanging over his head the entire time, but he just seems to forget about it so we can get our slugfest. (If you've seen it, you know what I'm talking about.) His whole approach to the fight was also weird. Why wouldn't Clark try to get the armor off Bruce, as opposed to trading punches? Rip off those giant gloves, and suddenly Batman can't hit you anymore! Take off his helmet, and his head's also unprotected.

Or why not just make peace? He tries to stop the fight once, for about two seconds, before just giving in to the madness. It seemed like he was angry about nothing in particular, since up to that point he's had no beef with Batman. He doesn't like Bruce's methods, sure, but Clark has no personal grudge with him.

And other characters seem to know certain things purely for plot convenience, and because the movie's racing to the fight. Like, how the hell did he figure that out?!
