Even without John Blackthorne’s literary-accurate massive dong, Shōgun is a ratings hit. FX pulled out all the stops, and as a result, 9 million views in the first six days of each episode’s release says a lot in the streaming age when there’s also a buffet of every other type of show imaginable. Truly great historical epics, however, are few and far between, and between this and The Bear, the network’s Hulu partnership is bringing the views in spades.
