Order of the Carmelites.
After every movie, my husband and I do a wrap up, sort of like a post game review. What got me was, the writers chickened out. In the comic Civil War, the fight between Captain and Ironman has high stakes and high consequences. If the movie had been willing to allow those sort of consequences to happen to both sides, it would have made the pain between them that much more than a mere stake out of my side, your side. Superhero movies do have to rely on action and pop, so philosophical musings about the consequences of decisions, of releasing/holding onto power have to be done on the fly. As Falcon says, "most fights don't involve that much talking." However, I think the intimacy of the fight fell a little flat because there wasn't as much talking as one would want, to bring the audience into the Civil war with genuine torn loyalties.
Talking it over with my husband, we have allowed as young as John to go see it, but I wouldn't let anyone younger.
