Moreover, Clark Kent can go places that Superman can't. Something I feel has yet to be properly portrayed in the movies.
See, that's what made Lois & Clark such an enjoyable show; they hit the balance between when to focus on Superman, and when to focus on Clark Kent.
Clark was much more than a secret identity. As an investigative reporter, he could go places, and follow lines of investigation that Superman couldn't. The story of the week often relied as much upon Clark's investigative ability, as it did on Superman's abilities.
