While well-reviewed during its first season, the changes to Agent Carter in Season 2 failed to inspire larger numbers and ultimately led to that show’s cancellation.
ABC has Agents Of S.H.I.E.L.D. already renewed and ready to roll out Season 7 after Season 6.
As noted prior, other projects have begun to move forward but not made it to fruition on the network.
However, the network has had trouble finding another Marvel mainstay.
