I have a soft spot approximately two miles wide for MCU Steve, before he gets the serum. It’s probably something vaguely maternal about wanting to protect him, but either way, I think he’s precious. There’s a bit of that here, but not that much. It’s a fun little story, even disconnected from the other stuff going on around it (like the issues of Steve’s death/resurrection, Bucky as Cap), but it isn’t very substantial. There were some bits of Cap canon that I wasn’t aware of — Anita Glass, mostly, but also the villain, Machinesmith.
It is fun to see Steve without his powers, to see that he’s more than his powers, that what made Steve happened before he was ever injected with the serum. I love the “phantom” shield that they’ve drawn in, so it’s clear he’s using the same tactics he learnt as Cap. It just seems right.
This title definitely isn’t a must, though.
