after Steve Rogers' resumption of the title has gone drastically downhill. It's decent espionage-ish superheroics, I guess, but the characterization is flat and the plotting unsurprising. There's nothing here that hasn't been done better before, often by Brubaker himself.
Post-Rogers resurrection Sharon Carter continues to be a cipher.
In retrospect, it seems very clear that what makes Brubaker's run so distinctive is Bucky Barnes -- the Rogers storylines derive much of their tension and emotional impact from the fall-out of his survival and trauma, and Bucky's attempts to deal with Steve's death and legacy are compelling. (Honestly, I kind of think of Bucky as Brubaker's Mary Sue -- but it's Mary Sue done right.)
