Or conversely, we could go the other way, with Clark as the much more developed, human personality and Superman as much more of an aloof, strong & silent type (a la the Fleischer cartoons). I can see either approach working with the right script, director and actor.
I'm all for that. I think after the Donner/Reeve movies and Superman Returns
that a new interpretation and approach to the whole Clark/Superman dynamic is needed. Reeve's approach- and to a lesser extent Routh's- is perfectly valid but I'd like to see a Clark Kent that is more confident, a bit more self-assured.
I think in order to believe that Clark Kent is a serious, legitimate reporter in today's contemporary industrialist climate, the buffoonish approach might be a little unbelievable. Superman can be the strong, silent type- it makes sense anyway since Superman is a sort of Greek god archetype anyway.
