When talking about future sequels, the usual topic of discussion is the villains.... but the real driving force behind all the Spider-Man movies has been the personal storyarc and conflicts of Peter Parker, and rightfully so. For example --- Spider-Man 1 - The origin story, nerdy Peter Parker becomes Spider-Man. Spider-Man 2 - He gives up, "Spider-Man No More". Spider-Man 3 - He finds and faces his dark side through the symbiote, and becomes "drunk" on the power it gives him, etc. The villains are basically just used to tie into the current story.... So what's next for the wall crawler in SM4?
