I'm a fan of Superman Returns, a huge one. I liked it more than Batman Begins. But I think that it's rather unfair to exclude those who liked Superman Returns to have input on what they'd like for the Man of Steel.
- Have Lex start up LexCorp.
- Introduce Supergirl, Supergirl doesn't deserve her own movie, but she's an intricate part the Superman mythos. Lets ignore the crappy Supergirl movie that has been retconned out by Superman Returns and the current crappy state of her comics. In Superman Returns, Clark said that Krypton was a graveyard and he was the only one left (asides from Zod, Ursa, and Non who were Phantom Zone criminals). I'd like to see Clark's reaction and response that he is no longer the only Kryptonian that is not a Phantom Zone criminal.
- Don't take out $10 million scenes.
- Have the villain be Brainiac, use the version from Superman: The Animated Series, he's way cooler.
- If Zod is the villain, have huge, epic battles with him! And in the end, have Superman kill him with kryptonite, just like he did in the comics.
- Have the movie set up for Darkseid!
- Just like Superman Returns mentioned Gotham, have more smaller mentions of the Batman universe (like how Superman: The Animated Series refered to Batman as "that nut from Gotham City" or a newspaper headline showing Batman) or even other places in the DC Universe (like Keystone City, Star City, Coast City, Central City, Gateway City, Hub City, Fawcett City, Happy Harbor, Ivy Town, etc.).
- Have someone who is involved in both comics and the TV/movie mediums to work on the script along with Singer, Harris, and Dougherty. Just like David Goyer did with Batman Begins. I recommend either Jeph Loeb or Paul Dini.
- I liked the style of Metropolis, but it just didn't seem bright enough. Show Metropolis as a more brighter place, no grey skies, lights everywhere. Make it seem that while they were rebuilding Metropolis from the damage Luthor caused, make it so that they took the rebuilding even further past of what Metropolis was, into the City of Tommorrow.
- Expand the Fortress of Solitude into a monument and memorial to Krypton, the House of El, and Kryptonian culture
- Superman Returns did a good job making Lex a darker character as opposed to his incarnations in Superman the Movie and Superman II, yet he still posessed some of the camp that Hackman's Lex had. Get rid of it. No wigs. No Lex doing some of the dirty work himself. No WRONG! No prison buddies. More "Gods are selfish beings in red capes who don't share their powers with mankind!" and the guy who stabbed Superman in the back with kryptonite.
