SERIES PREMIERE: You can think of this new limited ABC adventure series as either a prequel to ABC’s Marvel’s Agents of S.H.I.E.L.D. or a sequel to the 2011 Marvel movie Captain America: The First Avenger. Because it’s both. It’s set in 1946, with Captain America presumed dead, and his memorably effective colleague, secret agent Peggy Carter, relegated to a boring desk job. But as played, once again, by Hayley Atwell, she doesn’t stay trapped behind that desk for long – and soon takes off on a series of adventures and missions that require sexy disguises and quick-thinking bravado, like a period Sydney Bristow from ABC’s Alias. Count me in.
