Revealing that Coulson is alive would defeat the purpose of his death being the catalyst for uniting the team. Joss would not have done that. Coulson's death kind of reminded me of Wash's from "Serenity".
Agreed. That was too big a moment in the movie's story to just be undone with a snap of the fingers.
And the last thing I really want to see is him brought back as a superhero
. I want him to be the same deadpan SHIELD agent we saw before.
