Ok way late to this... But, I probably would have liked it, if each scene lasted more than two minutes. To me it felt like they took an eight hour movie and squished every scene down to a couple hours. The killing Zod thing, eh, not a biggie for me.
I agree that the fighting scenes were overkill, but the whole killing of Zod is flawed. Did you like Superman 2? Supes threw Zod down an abyss along with his minions.
People need to get over this killing of Zod crap. The writers have a plan & they have said it will be a main theme in the next movie.
