In a sense, one could argue that this goes back to the fundamental difference between comedy and tragedy. In Tragedy, the characters are over developed, and their psychology seems almost more than human, and more than real. I think perhaps Chekhov comes the closest, and one would argue the bulk of his stories tend toward the tragic. On the other side, one could say that Marco Polo in Calvino's Ctitą Invisibili (Invisible Cities), to use a more concrete example, is a comic genius, playing off the concept of women as compared to cities, and that they are each different and beautiful, yet all the same (I don't think it is hard to miss that every city happens to have a female name, and the features tend toward physical descriptions at times). Of course, the characters there are reduced to mere caricatures, and made less than human, as to be more comical.
I don't think that's too much of a stretch to argue. Perhaps Aristotle is still the most valid critic of literature.
