Re: What are your complaints? What would you do differently? *SPOILERS* - Part 1
First of all, I loved the movie the way it was. But one small change that would have made a huge difference in the ending battle was if Zod would have made the comment "If you love these humans so much, I will make you mourn for them" would have included the words "Starting with her" as he charges towards Lois.
I believe even with all the same destruction, if the scene had began with that difference and everything else in the final battle was exactly the same, far less people would have complained about the destruction or Zod being killed.
