I'm sure most reviewers enjoyed it. The creators had diligently studded the eps with period references: you get the radio serials, the Horn & Hardart-style automat, the fast talking high trousers male agents of the Strategic Scientific Reserve (SSR), and of course a busy office switchboard (and how much fun was it to see Agent Peggy Carter march smartly through a secret doorway, Get Smart-style, which magically appeared thanks to the deft movements of a switchboard operator?).
But I'm going to talk about the parts I loved.
