This issue is another in a long line of one of Captain America's staple features: characters flashing back to escapades in the war years. In this case, the theme is Bucky's various birthdays. I especially liked his 18th birthday in wartime Poland, where Toro's attempts to procure a cake get them all ambushed by Master Man and Warrior Woman.
Stories like this tend to be melancholy, but this is, weirdly, perhaps the lightest issue of this series in quite a while. It even ends on an extremely cheerful birthday party thrown by Black Widow and the New Avengers, with one of those borderline corny final dialogue exchanges as he blows out the candles on his cake (Mockingbird: "Wait. Aren't you going to make a wish?" "Nah..I'm good.").
I liked the brief return of the Watchdogs, too. A good callback to old stories.
Customarily great art from Luke Ross.
The backup "Captain America Saga" thing isn't much new if you've been reading the series, but it's got some really amazing images by Marcos Martin.
