Agent carter is a story of Peggy Carter who sees that she is demoted after the men from her country come back from fighting in a different country. As she is an undercover SSR agent she needs to make balance between her administrative life and helping Howard Stark who is falsely accused for providing dangerous weapons to the top bidder. She is also helped by Edwin Jarvis, to look for the real responsible person for the weapons supply.
To make Agent Carter work, and work well, Atwell and ABC knew she needed to be a relatable human first, and a subsidiary member of the populous Marvel universe second. Those priorities are straightened out efficiently on Tuesday's (opening) episode.
Agent Carter is ridiculously enjoyable. Despite not having the strongest story (another glittering orb Marvel? really?), the show is quick, genuinely fun, and Hayley Atwell is a damn delight as Peggy Carter.
