Right. I never read the comics firsthand, as I wasn't born until the mid-70s, but I have read all the Spider-Man stories from the beginning to the death of Gwen Stacy (and several beyond).

It seems to me that Norman Osborne was portrayed as either a somewhat broken man (after his memories of being the Green Goblin disappeared) or as an obsessive and perpetually angry man while he was the Green Goblin. I'm not sure where this magical charisma has come from, but this is the first I've heard of it.
