I have to highly disagree on this comment. If this was true, we might as well say that White and Lombard were useless as well and that would just be completely silly. That and the fact that we’re almost saying that Team Nolan/Snyder/Goyer are a bunch of dimwits putting characters who are useless in their films. And we all know that they are not dimwits.
Jenny Olsen although a small character in the film played a crucial role. Like Lombard and White, they represent the human race in the sense of helplessness, hopelessness and then bravery, chivalry, and of course HOPE. The scene where Jenny was trapped under piles of concretes was a representation of what we always know about Superman - he can’t save everyone and he can’t do everything on his own. He needs humans’ help.
So, Jenny had a purpose, and quite a deep one at that. She wasn’t placed in the film so she can just scream and look helpless. She represents that humans have hope.
I agree that the three Daily Planet employees put faces to humanity in MoS, and that it was important.
I was actually really happy that they were changing a big canon character like Jimmy Olsen into a woman - before I saw it. After I saw it I was pissed that they made her a typical damsel in distress, for no particular purpose. Why couldn’t Steve Lombard have been the one trapped in the rubble while Jenny and Perry bravely stood by and refused to leave him?
Or leave the other character, apart from Lois, who typically gets himself into scrapes and needs saving as Jimmy Olsen.
If they wanted a woman on the Daily Planet team, they could have made Steve Lombard female (hey Stephanie!) or added Cat Grant instead. Or, best of all, why not have Perri White, a fabulous African American female, be editor-in-chief of the Daily Planet?
