This is a collection of several different runs and arcs by different writers, so I'll review them individually.
Captain America #25 (Remender): This is the ending to a run, so there will be a bit that's hard to understand if you haven't read it. But all we really need to know is that Steve is now old, Sam is his best friend and a great hero, etc. The humor in this issue was cute and I loved seeing Sam get the shield.
All-New Captain America: Fear Him (Hopeless): Ehhhh. This one has an interesting dynamic, with Sam and Nomad (Ian Rogers) as partners, and Steve on the comms giving commentary and advice. However, the actual plot was pretty mediocre, and if you don't care about Ian Rogers, there's not much there for you.
All-New Captain America (Remender): This also follows Sam and Ian Rogers as partners. I think addressing Sam being seen as unworthy of the shield is a good choice, because it's realistic that racists would think that way, and Captain America is put on a huge pedestal in general. But it didn't do enough to establish Sam beyond that fear of living up to Steve and his desire to prove himself. Even Ian Rogers is someone who would make more sense paired with Steve as Captain America instead of Sam because of their history, which didn't help establish Sam as an individual in the role. The plot was also pretty silly.
3-Issue Inhumans Arc (Loveness): I don’t really care about the Inhumans and this was pretty filler-y. I loved the coloring in the Amazing Spider-Man issue and the sketchy quality to the art in the Inhumans issue. Overall, this was fine?
Captain America: Sam Wilson (Spencer): I adored the art by Daniel Acuna, and I thought the plot was the strongest of the collection as well. This again incorporates Steve as an old man, but this time it puts Steve and Sam in conflict over an ethical/legal issue. I thought it was in-character and a good way to involve him without simply making him an advisor or someone for Sam to look up to. He also doesn't seem to be taking over the whole story. Finally, Sam has his own team and side-characters. Other than Misty Knight, I don't love them so far, but I don't dislike them either.
Finally, this run gets very political. I would argue every good Captain America run should, but Sam's desire to be very clear about his political stances is also contrasted with choices Steve made as Captain America. It's also clearly referencing the political landscape at the time, since this run started releasing in 2015, months after Trump announced he was running for president. It's heavy-handed, but I don't have a huge issue with that. Although I will say, the narrative that America was "more divided than ever" and had lost the ability to talk to and understand their neighbor... I don't buy that Sam would necessarily see things that way. He's not from a privileged background and would instead be thinking about all the ways people had been divisive and bigoted from the very beginning. It felt a little clumsy. I also thought the Capwolf arc was unnecessary; maybe it's fun for one issue as a callback to Steve as Capwolf, but to have him running around in wolf form for three issues was too much.
Overall, I was disappointed with some of this, but I didn't flat-out dislike any of it. I would've liked to see a Black writer be chosen to write a Sam run, especially because I know he didn't have the shield for that long.
