Constructive criticism: Man of Steel

With Superman Returns not being the success Warner Bros hoped for, no more sequels that take place in the Superman universe that Richard Donner created have been made since. But since a reboot worked for the old Dark Knight it could work just as well for the big, blue, flying boy scout.

Young Clark: "What was I supposed to do? Just let them die?"

If it was my hypothetical kid from another planet with great powers who did something good and heroic I`d want the discussion to end on a positive note to give him the feeling that technically he did not do a bad thing.

Yes, I get that he did not want Clark to expose himself, but still. He died not because Clark couldn`t save him but because he wouldn`t let him. How about: Jonathan dies from a sickness. Yes it is similar to the Donner version but the difference is that in this version it doesn`t happen as suddenly and Clark gets time to say goodbye to his dad on his death-bed. Jonathan can remind him about the "Think before you act" bit, and say something about how he will change the world.

Movies are a visual medium and there`s a rule called "show don`t tell". Telling through pictures is a more universal language. Instead of Lois telling Superman what she went through they could have showed it in some way. From what I remember we saw what was going on in Superman`s head when they probed him but not what was going on on the outside. Here`s what they could have done: After we have seen Superman`s little nightmare landscape we could see what is going on outside his body as Zod`s voice keeps talking about how he`s gonna revive Krypton. We see him lying in an alien chair with a mindprobing helmet on and his face twitches as if he`s having a nightmare. Move the camera a bit to the right and we see Lois lying in an alien chair going through the same thing. Cut to: close up of Lois`s face, then cut to: inside Lois`s mind: pretty much the same thing we saw in Superman`s head. Cut to: close up of Superman`s face, then we go back inside Superman`s mind.
Yes, I said "lying in a chair". The correct word is "sitting", but I imagine them as kind of like dentist chairs... evil dentist chairs.

Besides that it would "look cool for the trailer", what reason is there for Zod to scare Superman with that nightmare-landscape? Shouldn`t he try to make Superman trust him and see him as a friend?
How about: Supes is shown what Krypton looked like before it blew up.
Zod: "Behold Kal-El, this what Krypton once was, and what it can be again." Clark wonders what would happen to the people of earth. Zod uses the cold, empathyless logic that "simpler civilizations will have to make way for the more advanced ones."
