SUPERMAN, PART 2
If Superman is not a closed text, in other words, if we can tinker with him, at what point does Superman (or Ulysses or Hercule Poiront or any mythical figure) lose his/her Supermanness? What essential characteristics cannot be changed before he disappears. Taking Superman as an example, I'd suggest his weakness in the presence of Kryptonite has to be inviolable. What others are essential?
Sorry if I am boring you, but the whole idea has caught my attention.
