Exactly. Just look at this lost dialogue from Superman II and tell me that it isn't straight from the SV characterization of Jor-El:
"Listen carefully, my son, for we shall never speak again. If you hear me now, then you have made use of the only means left to you - the crystal source through which our communication was begun. The circle is now complete. You have made a dreadful mistake, Kal-El. You have abandoned the world for the sake of private ambition. You did this of your own free will, and in spite of all I could say to dissuade you. Now you have returned here to me for one last chance to redeem yourself. This too - finally - I have anticipated, my son. (pause) Look at me, Kal-El... Once before, when you were small, I died while giving you a chance for life. And now, even though it will exhaust the final energy left within me... Look at me, Kal-El!... The Kryptonian prophe[c]y will be at last fulfilled. The son becomes the father - the father becomes the son. Goodbye forever, Kal-El. Remember me, my son..."
The SV Jor-El IMHO is in line with what Donner originally intended w/ the character, give or take a few aspects.
