Yeah I've heard Crowe's role is quite large, some have even said he stole the movie.
Well it's good to see they got the reporter aspect right. Still though her tracking down Superman is a tally very faithful to the comics.
I do honestly think that if we get a sequel that this film might be more fondly looked back on when we can see a larger picture.
Oh, the "Lois Lane investigative reporter" angle works fine for me. Just wanted to know a bit more about her. Then again, what did we know about Margot Kidder's Lois Lane? Oh right, she loved freshly squeezed orange juice.

Added a few lines about the expansion of Jor-El in the film, with a brief comparison of Brando and Crowe.
