After two impressive, if lowly rated, seasons, ABC pulled the plug on Agent Carter, the time-appropriate sequel to the first Captain America film.  Hayley Atwell portrayed the title character, Agent Peggy Carter, who worked for the SSR after WWII.  The series filled the gaps, both between the loss of Captain America at the end of the war and the current day Marvel universe and also during the hiatus of Agents of SHIELD on the ABC schedule.

Of all the shows that found themselves cancelled this year, this is the one I will likely miss the most.  There was tremendous talent involved in this show and it offered a certain fun spy vibe that no other show fulfills.  I certainly expect bigger and better things from Atwell in the future and hope the character shows up again, somewhere in the vast Marvel cinematic universe.
