Spider-Man 2 isn't an origin story, therefore, it isn't in discussion.
Iron Man didn't really do anything new, it was pretty formulaic. But the characters made the film great. And people say it wasn't that deep, that it was just a pop corn flick. I disagree to an extent. I mean there wasn't much action in it and THE best scene in the movie is one that doesn't involve the armour at all. I'm talking about the scene where Pepper threatens to quit. You guys know what I mean.
Virginia 'Pepper' Potts: Tony, you know that I would help you with anything, but I cannot help you if you're going to start all this again.
Tony Stark: There is nothing except this. There's no art opening, no charity, nothing to sign. There's the next mission, and nothing else.
Virginia 'Pepper' Potts: Is that so? Well, then I quit.
Tony Stark: You stood by my side all these years while I reaped the benefits of destruction. Now that I'm trying to protect the people I've put in harm's way, you're going to walk out?
Virginia 'Pepper' Potts: You're going to kill yourself, Tony. I'm not going to be a part of it.
Tony Stark: I shouldn't be alive... unless it was for a reason. I'm not crazy, Pepper. I just finally know what I have to do. And I know in my heart that it's right.
