Their's the problem
Unlike Batman, Superman is un-realistic , not to mention he really doesn't have an Extraordinary set of Rogue Gallery of Villains , His supporting Cast members aren't as dynamic as Alfred or Gordon (Dick, Tim, Barbara, Bullock & Montoya , Dr. Leslie Thompkins , and finally Selina Kyle) Especially once Jonathan & Martha Kent are gone . Lois Lane is a strong an integral part of The Superman mythology . But after her & Jimmy , Perry, Cat Grant (Supergirl & Krypto) Who else do you have ?
Batman is realistic? A guy wearing a costume at night like if it was halloween all year?
This is superhero genre movie and so fantasy is required not a established 100% reality.
But Do you want to see a "realistic" Superman?

Acclaimed by critics and Superman fans, it is one of the best Superman stories ever, even better than Superman:Red Son.
Supportive "cast"? Lois Lane and that's enough: not only it's a love story but basically one of big comic love stories everybody and I mean everybody knows: the Daily planet characters are more than enough and you want to add the Kents. besides, looking at batman, you have Alfred, Robin and Gordon while the others you have mentioned most of times are absent. Selina? Don't get me started...
The problem with Superman is that not everyone knows how write Superman: like The incredible Hulk (the Superherohype member) once said, Superman has to be an inspiration for everyone: men want to be like him and women want him.
What Donner did at the time was excellent but time is a train and it doesn't go back: Superman needs another treatment, another vision.
One of the things I like about Nolan's direction in telling Batman story is that he takes The best parts of What makes Batman the Iconic figure that he is with his supporting cast members & Rogue Gallery Of Villains and incorporates The Best (Graphic Novels, The comic book storylines & BTAS) to work up a good story in a Realistic fashion . Before he worries about how much action should be in the film. He focus more on making sure The story is both good but also believable . That why he's had huge success with Batman Begins & The Dark Knight .
As I've said before Batman Begins Rasied The Bar, Nolan Surpassed it with The Dark Knight, he not only raised the Bar really high now, But he's Redefined The Superhero Genre FOREVER . If he does decide on doing a Third film .
HOW THE HELL IS HE GOING TO TOP THIS EPIC MASTERPIECE ????
The thing about Batman and Nolan' s direction is, and think everyone will agree:
- the Excellent or better yet, perfect cast of actors
- A good foundation story and good story-telling
- Good production
Three essential things and they all have been covered.
Something which clearly failed in a certain movie...
