Re: It fails utterly and completely right out of the starting gate:
Its funny how you say that Norman Osborn is a ripoff of Lex Luthor when Normie was an evil businessman when Lex Luthor was still in spandex. As for the Joker, I'd say Carnage is more of a ripoff of him than the Goblin was. And not only is the "He only hates Spidey because he's crazy and mean" a huge oversimplification, but you might as well be criticizing 90% of the comicbook villains out there.
And the guy who wrote that article is probably the biggest Spider-Man/Green Goblin expert on the internet. Obviously that article is outdated now, but the majority of his points still stand.
