I don't think Kramer is a good example of this. The Simpsons characters, and I suppose most Friends ones as well, gained depth (or at least the audience's affection) over the course of several seasons, whereas Seinfeld stuck to its original formula of, "No hugging, no learning." Kramer was never supposed to take on interesting dimensions like the Flanders of the nineties did.
