Yeah I agree. If they did Goblin again, I would love a suit closer to the original though, instead of the sort of plated armor, something more tailored. With the purple thrown into the green mix.
However, a movie with Electro, Vulture or Mysterio for example would be more exciting because they could do things they haven't before. Plus, they've already had the Goblin once, so if they do it again it's a lot of pressure to make it good, otherwise people will see it as the "worse Goblin movie", but being a Spider-Man movie I think pressure always comes with it.
