I enjoyed this movie quite a lot the stark differences between Steve and Natasha worked well together as for the first half of the movie everyone is crazed at the attempt on fury’s life that they refuse to trust anyone including each other especially knowing that shield has been invaded by hydra. There is a lot of character development in this movie especially when James Buchannan Barnes (Bucky) comes into play and Steve has to get over the instinct to protect his best friend and save the world instead.
There’s also a lot of character development for Natasha seeing as she is learning that shield, the agency she believed was good and would clear her guilt was actually secretly infested by the agency that has never done any good, much alike the institution she was raised in (the red room) where she was an assassin for the KGB, an institution she would never want to work with again.
I really enjoyed this movie and its portrayal of trust, its one of my go to films so I do recommend even just for a re-watch.
there's some interesting thoughts about character development in this review, very interesting
