Some points I'd like to address from other posts:
- Snyder has said this Superman would be more vulnerable and have altered powers, so he wouldn't appear overpowered. I'm not sure what I think about that right now, but it can only make the movie more interesting. The Marc Webb Spider-Man seemed more vulnerable than the Sam Raimi incarnation, and I liked the new one better.
- This movie is
intended to be darker, more serious, and less campy than other versions. It might take on a similar vibe to Batman Begins, which has been said by those who saw the longer trailer at SDCC. From what I see when people write about Superman on the Internet, a lot think he can't be taken seriously. I've heard the word "pansy" being thrown around to describe him. So, here's your darker, more serious Superman.
- Having said the above, I can safely assume General Zod will be a very brutal, formidable villain, and having said that, he should have extreme douchebaggery.
