and that would be fine... if they actually mined that story more and really gave it as the motivation for Tony retiring, but it was so glossed over. and even if they were going to do that as is, he literally JUST retired in the last Iron Man 3. they hit the same beats over and over again and it's just getting tired.
along the same lines... they keep killing characters in their movies... trying to make big emotional moments and then reviving them. They've done it with Loki TWICE, Agent Coulson, Nick Fury and now Jarvis. They've gone down the Rocky road of having to give motivation by killing their Mickey/Apollo's... which is pretty weak in of itself... but at least those guys STAYED DEAD. Hell, I wouldn't be surprised if Quick Silver somehow came back to life in the next Avengers movie at this point even though he was riddled with bullets.
I think this is lost on comic book fans because in the comic book world, nobody is ever dead. Even when they die huge, epic emotional deaths like Superman in the 90's, they just come right back. Gotta keep selling comics, gotta keep making movies.
I agree tho it is weak and I swear that is exactly the conversation I had with my daughter after the movie:
"I loved it but I'm sad that Quicksilver is dead."
Me:
"Oh dont worry about that I'm he'll be back."
It's a staple in comics and they have carried it over to the movies now, just look at X men, hell they just resurrected EVERYONE! lol Atleast they explained how and why everyone is now alive tho.
