I don't think it'll be anything more than a loose adaptation of the principles behind Civil War - oversight v. freedom. Civil War is just a comics buzzword at this point, something that generates hype even if attaching it to a given thing makes no sense.

Having said that, I'm hyped out of my fucking mind for this movie, now. Seeing Tony develop into his Civil War version played by RDJ is insane to think about, and I think they'll really do it well, so long as they don't try to make this Civil War on the big screen. Because, obviously, it can't ever be that.
