What I would like to see is Clark Kent in action. I don't want the dumb persona, but the strong character he is in comics. I mean...the pullitzer winner...the clark who was not a loser =\. Perhaps showing us why he chose to work in a newspaper in the first place. Using his connections to unravel the mystery behind the big bad guy.
The bad guy should be someone imposing. Someone who threatens Superman and therefor the world. I don't care if an enemy is terrorizing the city if I know Supes could just end it if he just let aside his morals and ethics. I want to see him get pushed physically and emotionally. Having to come up with a tough decision. Perhaps even killing a villain because he had no other choice and then showing us the consequences it had in his character and how it shaped him.
I want no Lex. Villain could be someone like Zod...Mongul, even Bizarro if done right. Kindda like showing us why Supes is so scared of going all out by using Bizarro as a contrast. Metallo could work too. There are a lot of possibilities. They just need to be willing to forget the last movies and focus on a new generation of kids/adults that watch these type of movies.
With all the super hero movies out there you'd think they would actually give other villains a chance.
All in all its time to kick nostalgia's ass and move on.
