Somewhat replying to Spence's thread, with regards to the series, I personally am far more interested in the "slow" stuff about Sam's feelings and Louisiana family than the small-time threat posed by a handful of refugees, enhanced strength or no. I agree their motivation should have been explained earlier than it was, and it turned out to be more believable than I was expecting, but their rallying cry/dream of a border-free world is still laughable, and dooms them to failure and long-term irrelevance, no matter how many hostages they take or hospitals they blow up.
Instead, this story is primarily about how Sam decides to become Captain America, regardless of who nominated him. Its heart lies in Bucky's line that neither he nor Steve understood what it would mean for a Black man to carry the shield. There was beautiful storytelling in following Isaiah Bradley's declaration that no self-respecting Black man would want to be a Captain America with the scene of Sam's Black nephews happily playing with the shield. They think nothing of it, Bradley is against it, and Sam is in between.
Sam's limited finances don't make a ton of sense, either, given his celebrity status, but they make for a more compelling story. And I'm delighted to see that the weak third episode was very much an outlier.
