6. 'Masters of Sex': Heartbreak Hotel
The episode "Fight" sums up everything that makes Masters of Sex so devastating. The 1950s sex researchers — played by Michael Sheen and Lizzy Caplan — sneak off to a posh hotel, under fake names, for a little horizontal (and vertical) (plus diagonal) lab work. Strictly business, all in the name of science. But all the bedroom role-playing opens up the NSFW feelings they spend the rest of their lives ignoring. They expose the flesh under their bathrobes — as well as way too much of the pain under their flesh. An hour of erotic agony, from a drama that never plays it safe.
