For all intents and purposes, Peggy Carter (Hayley Atwell) is a '40s Emma Peel, and her companion, Edwin Jarvis (James D'Arcy), though never pretending to be Patrick McNee, invokes John Steed.
In the initial season, Carter helped Howard Stark (Dominic Cooper) clear his name after a complex frame-up. Season 2 (premiering Jan. 18) will focus on Carter's move from NY to LA (along with some hardy Hollywood glitz) during the onset of the Atomic Age. What thrills such will bring is yet to be seen, but I suspect it'll be pretty darn good, particularly with a promised Doc Strange connection characterizing the plot.
Season 2 also reinstates Chad Michael Murray as James Thompson and Enver Gjokaj as Daniel Sousa, with a reappearance by Cooper/Stark and an anticipated, dance-number cameo by Lindsy Fonseca as Angie Martinelli. (I can only imagine that continued Cap references will again be part of the proceedings.)
While "Agent Carter'"s companion series, "S.H.I.E.L.D." generally hits a more adventurous note, it also tends to get muddied by various espionage tangents. The nice thing about "Agent Carter" (so far) is its simplicity: in my estimation, the best way to tell a good-vs-evil tale. Now, let's just hope the new season extends that wise tradition.
