The actor is fine. Black Captain America who is also the Falcon? That also has potential to be neat. Lot of interesting dynamics to explore there.

Then the show came out, they barely touched the race issue and instead made him Captain Liberalism, complete with an incredibly cringey speech at the end.

Falcon and the Winter Soldier is probably the worst case of "Villain has a point, better make them burn down an orphanage or something" since Black Panther overthrew the anti-imperialist lawful monarch of Wakanda with the help of the CIA.
