Not having Agent Coulson stay dead creates little sense or danger or repercussion in the Marvel Movie Continuity. Opinion further validated by ending of Iron Man 3.
Yes I know it’s a adapted comic movie series but I’m looking at it from a screenwriter’s POV.
It’s not entirely unpopular. I’ve definitely seen it around.
However, I’m personally optimistic, and that was reinforced by this interview.
Snipping the relevant segments:
Clark Gregg: The executives at Marvel had joked about being in meetings where they were talking about how to bring Coulson back, but you know, I was there. There was a lot of blood. I felt pretty dead. So I was wary as to how can we do that in a way that doesn’t feel like it undermines any of the magic that I thought was there in “The Avengers,” and as soon as I heard the concept and saw the script, I realized it was worth doing.
Joss Whedon: And then, you know, “What about Coulson?” And obviously, the first question, was, “Will this upset the integrity of what we did in ‘The Avengers?’” You don’t want to do that. I worked in comics and TV and fantasy for a long time, and I know that there’s a right way and a wrong way to do stuff like that.
It’s like, “If we were going to have Coulson, how would we even do it?” Well, we’d do exactly this. That’s what I pitched to [Clark] on the phone, that’s what’s in the script, word for word, and it’s all about earning everything, so that people don’t feel that you lied, or that you pulled one over on them, that you have an explanation that you buy.
So, like I said, optimistic. Because they’re at least hyperaware that they have to do it right.
