I liked that the bad guy in this one wasn't some big super-powered villain, but a fairly regular guy, maybe more intelligent then average, who had a tugboat load a hate and bitterness. His attempts to play the heroes against each other was fairly well done. Still, having them chase him to a far-off Soviet bunker in the middle of nowhere was a bit of a stretch. He could have shown Stark the video without, for example, having to bomb the treaty meeting. And I'm not sure why the existence of other Winter Soldier types was some important to him, and why he wanted to get rid of them.
If there was one thing I was waiting for, it was for someone to point out the obvious fact about the previous conflicts such as Sakovia (sorry if that's spelled wrong)--the Avengers and other heroes didn't cause those conflicts, they were simply responding to what Hydra and Ultron were already doing. If anything, they kept the disasters from being worse then they were.
I guess I don't like it when the good guys get blamed for the damage and injuries and deaths that the bad guys cause. In the middle of the discussion about signing the UN agreement, I was wondering "Who's going to keep the bad guys in line?"
The disagreement between Cap and Stark was well done, neither came off as being the good or bad guy. It's the kind of situation where good guys could honestly disagree with each other, and there is no perfect solution. It's not a moral dilemma, where there are obvious good and bad choices.
Maybe I should have seen it coming, but the twist at the end that set the big fight in motion between Cap and Bucky and Stark caught me by surprise. But it also had the one scene I didn't understand, when WS looked up at the camera before shooting it. It seemed like a secret killing machine like WS wouldn't let his face be so plainly shown.
I really liked this movie, and I'll probably try to see it again next weekend. I think it at least holds its own when compared to BvS, which I liked a lot, too.
