nope, will take a miracle to be truly good
superman is one of the dumbest comic-book characters of all time
he's way too powerful and his only weakness is way too convenient and thus any conflicts seem way too contrived
Doctor Manhattan from Watchmen makes a far more interesting ultra powerful character. But they won't rewrite Superman in a similar fashion simply because he's just far too ingrained already to be well received by the diehard fans.
Actually Superman COULD be a great character. Yes, they made his powers ridiculous back in the 60's-80's...much like they did The Hulk over at Marvel.
The 1990's Animated Series showed that great, interesting, and moving Superman stories were possible. The last movie failed because it tried to emulate the corny Christopher Reeve version mixed in with some modern Twilight emo crap. They need to start fresh and make a more vulnerable Superman, then it will work nicely.
What made the 90's Animated series great were things like:
- high caliber weapons could push him back and stung a bit
- he couldn't be in two places at once
- he wasn't "super-intelligent"
- he had limited strength, mostly because he had to hold back to avoid hurting people
- he made flawed/emotional decisions
- living a double life is more difficult to handle than it seems
Here's some examples of great Superman stories, and they really need to take these tips in the movie:
