I'm not really a comic book guy, so I don't know anything about Steel's origin story.

But if they were to make a Steel movie today, the first thing they'd do is show how he was stronger, faster, and better than Superman, and how everybody loved him more right away. And Superman purposefully kept Steel out of the spotlight because he was really an insecure mediocre white man who actually stole his powers from Steel, and even when he had his stolen powers he wasn't really that great to begin with.
