ASM2 has got to be set in college. Garfield actually did look like a teen but he wont in two years time.
I agree.
What I want for ASM2:
Starting college (but no stupid sub plots about Gwen going to a different school to create forced unneeded tension. That seems like something Orci & Kurtzman would do)
Formally introduce Norman Osborn in person as an important character (but no Green Goblin yet)
Introduce Peter to the parent conspiracy, move it along, but don't solve it yet (In the first one all he knows is that his parents left without reason, he doesnt know about the oscorp conspiracy yet. Let him in on it)
I also want them to expand on the things that got deleted from the first movie, hinted at in trailers and in the video game. Something about Peter is special, which keeps him from turning into a Man-Spider like Connors did with lizard DNA.
Keep Dr Connors around as a side character in this conspiracy (recurring side role)
Mysterio as the Villain (he seems like the most likely, entertaining choice while not doing what has already been done in recent years)
More of the more quiet and sweet moments between Peter and Gwen.
Give the Daily Bugle more presence in the movie, maybe even show JJJ on television a couple of times. (But don't have Peter work there or interact directly with JJJ yet. No need to rush, but showing that these things exist without making a big deal about it make the world feel larger. Much like Oscorp and Osborn in the first one)
Also, have JK Simmons play him again. Just...just do it. Maybe have him tone it down a bit for this more realistic movieverse, but just do it.
Don't do the cliche thing and kill off the villain. My friends and I all loved that Connors was left alive (for a change). Makes it feel more like the world of the comics, making me imagine all the the future tangles the characters might have even long after the movie series is over. It just makes the world feel so much larger.
Also, it seems like Sony and Marvel/Disney might want to start playing nice soon, with Oscorp almost being in Avengers and the stuff Avi Arad has been saying lately. Work it out, get Avengers Tower in the background of a couple scenes, get Fury or Stark in an after credits scene observing Peter as an up-and-coming future candidate for some involvement with Shield!
