The kid played with a trash can on his head partly because he was a kid, and partly to show the audience that he did not yet have x-ray vision.
"I thought Kidder embodied her perfectly. Up till that point she was a more or less one dimensional character. Kidder gave her some quirky pizazz"
I didn't think it at the time, but later on, looking back on the depiction of the character it seemed that Kidder's Lois Lane was a coke-head. She was an anorexic, hyperactive, work-work-work reporter. Superman scolded her for smoking, but he should have checked what else she was doing. On the plus side, she was into healthy fruit juice.
My out-of-the-box suggestion would be to have Superman appear via some dimensional accident in a universe similar to ours -- a universe without superheros. But also a universe without comic books or else it would get cheesy fast. So no one knows who the heck he is. He'd have to prove himself to a world that is cynical and doesn't even believe he is real. Or maybe not. The problem with comic book movies is how to avoid the existence of comic books. It's almost impossible.
But if he stays in the DC universe, I suppose I'd do what Superman II did -- introduce Super Villains. And maybe an easy way to do so would be for that growing-planetoid that Superman lifted into space (in SR) to continue growing, and for its crystals to start becoming infused with intelligence, and for it to create some humanoids to send down to Earth to mercilessly begin researching. But not in a library. By tearing things apart. Maybe there's more than one or two. Maybe it sends down hundreds of people-looking forms and no one knows who is human and who is a super-villain until their friend or partner tests them. Even if Superman destroys the planetoid, those people-shaped forms would still be wreaking havoc on Earth. Cameo by a CGI Marlon Brando to serve as the planetoid's evil (twisted) intelligence. No goatee. Just evil by being purely scientific, without ethics. The evil of Nazi scientists. Or maybe the planetoid is slowly repopulating the Earth with reproduction (flawed reproductions) of all the people of Kypton. So eventually Superman finds that all these replicants are plotting to take over the Earth as their new home, even though they're not "real". And Supes would object. An anti-colonialism message perhaps?
We can guess that Singer's plan for the sequel may have involved the planetoid since
Parker Posey's character very explicitly dumps the "smart" crystals out of the helicopter onto the crumbling surface. (Lex screams at her "what did you do?!!!" in anger). Singer had some reason why those key crystals, those databank crystals with the accumulated knowledge of all of Krypton, got left on that growing body.
