Green Goblin...it was just a bad move to use Spidey's greatest villain in the first movie. It makes sense in the bigger picture of building up this Goblin legacy where Harry Osborn ends up taking the serum as well, but I would scrap all of that to see GG appear after the first film while developing Norman Osborn beforehand.
