There's a lot of arguments over the decision to have Superman kill Zod at the end. For some that is the deal breaker, ruining the whole film for those fans. Then there's those who really don't think of it being that big of a deal because of the way it was handled. A good contrast is SUPERMAN II where Superman kills Zod with a smirk on his face. Where was the outrage then? I think it was a bad call, but it doesn't necessarily ruin it all for me. Either way, I think the positive thing this brings is that it gets people talking about Superman, making this iconic character once again relevant for the first time in awhile.
