Naming Superman

In the original 1978 Superman movie, Lois Lane names Superman after he has flown away from his interview with her using the following line of dialogue...

"What a super man. Hm. 'Superman!'"

In "Superman: The Animated Series", the cartoon Lois Lane also names Superman, except in this case it is in a meeting with her editor after Superman's first public appearance.

"He's strong. He flies. He the Nietzschean* fantasy ideal all wrapped up in a red cape. The superman."

(Friedrich Nietzsche was a German philosopher whose perfect Übermensch or "superman" was a goal he suggested humanity should aspire to.)

How is it that a cartoon manages to produce a more intelligent, less forced, better written, more believable and far superior origin for Superman's name than a Hollywood blockbuster?

"What a super man," indeed!
