Yeah I gotta hard disagree with that.
I've never found Lois superficial or shallow, nor do I think her being drawn towards Superman is a school girl crush.
In interpretations where Clark actively pretends to be a bumbling fool, to keep anyone from really seeing him - surprise surprise, she doesn't see him. When he's more himself as Superman, she sees him.
In interpretations where Clark is more himself as Clark, like LnC for example, it plays out as more like a defence mechanism. She keeps Clark at arms length and goes after the unattainable hero because she's afraid of being hurt. Until she eventually let's her guard down.
It's very simplistic, and kinda missing the point, to think she fancies Superman for superficial/shallow reasons in any interpretation. Even Bosworth.
