I really want a more serious film. I'm not saying that it needs to be more realistic just less campy. Which is most likely the route Nolan will go. Here are some other things I would like to see
1.I don't want to see the same Lex from Donner's films. The comical real estate loving wannabe criminal has to go. We need a sinister evil genius looking to become President by any means necessary.
2. Superman def needs someone to punch or else it just gets boring. If you subtract Batman, and take a note from Public Enemies. Metallo would be an excellent move for the Man of Steel.
3. So far in recent movies Superman has been in the spotlight taking Lois Lanes interviews being publicly seen. I think Nolan wants to take a step back, and make him more of a mystery which is the route I prefer.
4. A set up for possible sequels. Superman II is basically the only movie that can be considered a sequel since we see Zod come back as the villain. If this movie sets up Brainiac as the villain for a sequel my dreams will have come true
5. Finally- I demand a hot Lois Lane
I'm sure most of this has been stated before, but when it's a good idea sometimes it needs to be said more than once.
