Here's my question (and no, I haven't seen the movie yet).
How can we ever take a solo film seriously again? If they know there are other heroes out there why bother taking on any future supervillain alone? Why not just Assemble again and do it as a team?
The issue (at least for Iron Man 3) has been addressed by Kevin Feige
"Iron Man 3 has been structured specifically to be the antidote to The Avengers," Feige said. "Circumstances in the story separate Tony from having access to anything.
"We wanted to take Tony back to, metaphorically speaking, the cave from Iron Man, the first half of Iron Man, when he's cut off from the world and needs just focus on his intellects to get himself out of his situation.
"So he's not calling Thor, he's not calling Captain America, he can't press a special button to have the helicarrier come rescue him, so I think that'll be a nice complement to the team-up of Avengers."
No Black Widow in IM3 either, boo. I hope they make a SHIELD movie then, definitely need to see more Fury, Nat and Barton
