Is this perfect?
That is up to each viewer to decide, but as far as setting up "possibilities" and giving you a solid grounding in why you should care about these characters... that it nailed.
The loss of Cap, resonated...
I will give a contrast, I watched something earlier that was 5 years in the making and lasted 4 hours and character was done much cleaner and kept more consistent in this (Sam's need to come to the rescue, Bucky's hesitancy to open up).
It showed, why Falcon was an Avenger outside of being Captain America's buddy and man am I rooting for Sgt Barnes.
I liked the secondary characters, like the military guy who helps Sam, the angry old dude, yelling at people over trash, the guy in the wrong place at the wrong time, the waitress/bartender, the Sister, the guy who just needed $50 more bucks til tuesday.
I like how they used Batroc
I see this as a buddy cop film, but with Riggs (Lethal Weapon) and Mike Lowry (Bad Boys) as the team up.
I am all in... "On your left"
