I think all those videos are going to make this go viral (in the MCU) immediately. This won't look good for the US, and if people get Sam and Bucky in those shots, it won't go good for them either.
The writing on this show is top notch. No reason to not expect that. Just pointing it out. Lots of good social commentary. There's really two ways to do social commentary - naturally, or shoving it down our throats. With the amount of commentary they are doing, it would be very easy to shove it down our throats, but I feel like they're doing a good job of showing, not telling, us all of these things. The struggle of the black man. The follies of perfection and nationalism. Extremism. Heavy stuff.
Can't say I'm surprised tho. Captain America was always the hero of the Avengers that appealed to me in the 80s, and of all the different franchises within the MCU, it's the franchise that appeals to me the most. This series has definitely carried that tradition on for me.
