Civil War was a great concept that had poor execution. The problem as I understand it is that they eventually turned Iron Man into a fascist and portrayed the who Pro-Registration side as straight-up bad guys. If they play up the moral ambiguity and have both sides portrayed as having valid points (and let's face it: they do) like they said they would, they could make it work this time. Hell, they already have the Winter Soldier in place. I would totally be down for them going full-hilt with the death of Captain America storyline. You know, provided that they make it stick. I adore the Cap and all, but major character deaths lose their meaning of they're always temporary.
