This was a solid finale. Much stronger and more satisfying than WandaVision's.
I have my issues with Sharon/the mid-credits, and I think Sam's speech was slightly clumsily handled.
But I'm just giddy seeing Sam as Captain America, and I think the episode had a great balance of action and character.
A strong action climax where I just loved seeing Sam in action, that also furthered Sam and John's characters, a fairly good wrap-up of the moral of the Flag Smashers, and then adequate time spent wrapping up the characters' personal stories.
I particularly adored the Isaiah museum scene.
I feel satisfied with the finale and the show, and am excited for the future of Sam Wilson's Captain America.
