See, here was my gripe with the ending. I mean, it's one thing to have a staunchly-anti-killing superhero kill: with the exception of Batman, most of them have been pushed to it in some way or another in extreme circumstances, but the bigger issue with Superman killing Zod in the movie was that it was such a bland, LAME decision. "I can't beat you, so I'll force you to kill me or I'll kill this photogenic white suburban nuclear family!" I mean, come on. That is the most basic, childish, surface-level, black-and-white portrayal of the "to-kill-or-not-to-kill" choice. If you want to subvert the superheroic code, at least find a more nuanced way to address it.
