Dr. Moynihan orders 5cc of Haldol to be administered to Lucky Emory. The show is set in 1953, but Haldol wasn't discovered until 1958 and not approved by the FDA until 1967. Thus this medication didn't yet exist.
I left the final 3 episodes to watch one night because I enjoyed the first 7 so much. It literally just fell apart at the end. So disappointed. I can't even describe what happened or why. Just a disjointed mess of a final episode. I gave it 4 stars because the acting was stellar.
