And that, Kilroy, is why you don't do the Sinister Six in movies. Because you can't do all that without either stripping them down to something more basic or crowding the film with way too many villains.

Also, Green Goblin not confirmed, regardless of how obvious or may or may not be. The previous Spider-Man movies' Dr. Connors never got to be the Lizard outside a semi-canon video game.
