I can agree with Stew on Bucky being the main thing feeling kind of weak. Now, I totally understand Captain America standing up for him and defending him--especially when those cops are coming in with orders to kill and not even attempt to take him alive. If Captain America explained the situation and they still come in guns blazing, even if Bucky says he's willing to surrender, then by all means, take them down.
But at the same time, if the government is calling for Bucky's arrest, then it's kind of hard for me to believe Captain America would not stand down. He'd support Bucky, sure, and fight on his behalf in court, but straight-out treason over it? Hm...I believe there's going to be a bit more revealed. The government over watch thing is probably a good start.
Love Iron Man's line, "So was I," because it just stings. It sums up everything that is wrong with the whole situation they've all found themselves in.
Wonder how Black Panther will play into all of this. Captain America is chasing him it seems, but why?
