I understand why it's a polarizing movie. I also think everything compelling that can be said has already been said. At this point, it seems like what I've often seen is people arguing for the sake of arguing.
"This is why Zod's death was okay!"
"No, this is why it isn't!"
Everyone has made up their minds at this point and I sincerely doubt anyone is going to say something that'll give someone else an epiphany. But hey, if people are cool with going down that road a gazillion times, have at it.
