ONCE AGAIN:
Does the general public CARE about these minute details? NO.
To them, another Goblin is another Goblin, I don't care how you dress it up, it's still a Goblin.
What does that even matter? He was a quiet villian because he only had it in for Peter.
And to the both of you who still insist Harry was a GOBLIN villain, here's something for you to hear...it was from Sky Two, a British television channel and I read it on wikipedia.org also...James Franco was given an interview and he mentioned about his character Harry Osborn in the third installment:
Harry Osborn does not wear the costume aimed at terrorizing people like that of his father, but wears a streamlined costume solely for the intent of killing Spider-Man.
He doesn't beomce a full-fledged goblin character like his father, because he's not a true goblin villain...he's not Green Goblin, he's not Hobgoblin, plus he doesn't look like a goblin, PLUS his name was gonna be called like the Night Stalker or something like that beforehand, until they came to the conclusion of just calling him New Goblin, just to please fans...which is weird, Spider-Man 3 was obviously meant to just please villains, i.e., calling Harry New Goblin, having the symbiote/Venom/Eddie Brock in it and also having Gwen Stacy in it.
