Interesting question, considering what's happening currently.
More like the supporting character she was in the early S&S years, an observer and witness of Superman’s activities and doings and sometimes critic,
from a human point of view, of this powerful being who chooses to use his powers in a benign fashion to oppose injustice and criminal oppression.
An investigative journalist with loads of curiosity and lots of courage in following a story which creates the risks where Superman has to intervene.
Not just a headline chaser or ultra-feminist with agendas but, someone self-contained and confident in herself and what she is able to do
in the job she has chosen to do without pretention or boastfulness.
Most of the time she helps and supports Superman but, can have disagreements on occasions when
she believes in other choices he could have made.
I would say the best recorded example of this was the portrayal of Lois by Phyllis Coates in the first season of the
George Reeves TV Superman series in the 1950’s. She was replaced later by Noel Neill
who had played the role in the two Columbia Pictures movie serials in 1948 & 1950.
Neill’s softer approach was also valid and engaged lots of fans but, my preference is for the Phyllis Coates incarnation.
