I saw it and if I had to some it up in a word, I'd call it "satisfying".
It had me worried about half way through about the should we/shouldn't we argument not really carrying any weight for a cataclysmic climax. So I was glad and surprised to see it focus on something a bit more primal, vengeance, instead.
That last scene of them fighting Tony was incredible. Absolutely perfect.
Now the film does have problems. One big one is that the debate is never truly debated. They had one scene and Tony gave a couple quips about Aliens and Ultron, but where is footage of other inhumans or heroes breaking things and killing people? Vision mentioned how Ironman started a movement, but there was no footage of it. Where is Cap saying that the government wanted to nuke an American city? Where is Tony talking about relief funds for Avenger ****-ups? Where is Black Widow talking about how governments can't be trusted due to first-hand experience? What about how Hydra infiltrated Shield? Could that happen again? Why is Antman not on Tony's side? Wasn't he trying to fly straight and see his girl? Where are the average citizen protests? Other than one mother, we saw nothing of the citizenry getting pissed off.
All in all, it made for a real lack of conflict. It never truly felt like they were fighting one another with conviction and that's why the last scene is so great. That conflict felt real and therefore, so did the fight.
